c6a13f3d6f arm64: gic: Add power up sequence for GIC-600
Arm's GIC-600 features a Power Register (GICR_PWRR),
which needs to be programmed to enable redistributor
operation. Power on the redistributor and  wait until
the power on state is reflected by checking the bit
GICR_PWRR.RDPD == 0. While running U-Boot in EL3
without enabling this register, GICR_WAKER.ChildrenAsleep
bit is not getting cleared and loops infinitely.
This register(GICR_PWRR) must be programmed to mark the frame
as powered on, before accessing other registers in the frame.
Rest of initialization sequence remains the same.

ARM GIC-600 IP complies with ARM GICv3 architecture.
Enable this config if GIC-600 IP present.

9f5df9a3ef rockchip: include asm/io.h directly in asm/arch-rockchip/hardware.h
The different macros use writel which is defined in asm/io.h, so let's
include the header so users of hardware.h do not need to include
asm/io.h as well.

While at it, remove asm/io.h includes wherever
asm/arch-rockchip/hardware.h is included already.

8ed8517d9e rockchip: rk3588: add constants for some register address spaces
It's one thing to have the register mapped via a well-defined struct but
it's another to be able to make use of it. For that to happen, one needs
to cast the physical address memory of the beginning of the register
address space with the struct. Since this cannot change, let's hardcode
it in the include files so that users do not need to duplicate this line
of code in their own implementation.

5d710738bb rockchip: rk3588: disable force_jtag by default
Rockchip SoCs can automatically switch between jtag and sdmmc based on
the following rules:
- all the SDMMC pins including SDMMC_DET set as SDMMC function in GRF,
- force_jtag bit in GRF is 1,
- SDMMC_DET is low (no card detected),

Note that the BootROM may mux all SDMMC pins in their SDMMC function or
not, depending on the boot medium that were tried.

Because SDMMC_DET pin is not guaranteed to be used as an SD card card
detect pin, it could be low at boot or even switch at runtime, which
would enable the jtag function and render the SD card unusable.

This is the case for RK3588 Jaguar for example which has an SD card
connector without an SD card card detect signal and has SDMMC_DET
connected to ground.

Because enabling JTAG at runtime could be a security issue and also to
make sure that we have a consistent behavior on all boards by default,
let's disable this force_jtag feature.

However, let's make it easy to reenable it for debugging purposes by
hiding it behind a Kconfig symbol.

Note that soc_con[0] is reserved. But considering that it's way more
user-friendly to access soc_con1 from the TRM with soc_con[1] than
soc_con[0], and that soc_con0 would actually be located at 4 bytes
before soc_con1, let's just make soc_con0 part of the soc_con array.

0d5104cdb7 rockchip: rk3588: Fix boot from SPI flash
The commit fd6e425be243 ("rockchip: rk3588-rock-5b: Enable boot from SPI
NOR flash") added a new BROM_BOOTSOURCE_SPINOR_RK3588 with value 6.

At the time the reason for this new bootsource id value 6 was unknown.

We now know that the BootRom on RK3588 use different bootsource id
values depending on the iomux used by the flash spi controller, and not
by the type of spi nor or spi nand flash used.

Add the following enum values and use them for RK3588 boot_devices.

- BROM_BOOTSOURCE_FSPI_M0 = 3
- BROM_BOOTSOURCE_FSPI_M1 = 4
- BROM_BOOTSOURCE_FSPI_M2 = 6

Keep track of the re-entries with help of the lr register.
This binary can be re-used and called from various BROM functions.
Only when it's called from the part that handles SPI, NAND or EMMC
hardware it needs to early return to BROM ones.
In download mode when it handles data on USB OTG and UART0
this section must be skipped.

Unlike newer Rockchip SoC models the rk3066 BROM code does not have built-in
support to enter download mode on return to BROM. This binary must check
the boot mode register for the BOOT_BROM_DOWNLOAD flag and reset if it's set.
It then returns to BROM to the end of the function that reads boot blocks.
From there the BROM code goes into a download mode and waits for data
on USB OTG and UART0.

beeace9ba1 sunxi: refactor serial base addresses to avoid asm/arch/cpu.h
At the moment we have each SoC's memory map defined in its own cpu.h,
which is included in include/configs/sunxi_common.h. This will be a
problem with the introduction of Allwinner RISC-V support.

Remove the inclusion of that header file from the common config header,
instead move the required serial base addresses (for the SPL) into a
separate header file. Then include the original cpu.h file only where
we really need it, which is only under arch/arm now.

This disentangles the architecture specific header files from the
generic code.

95168d77d3 sunxi: add Allwinner R528/T113 SoC support
This adds the remaining code bits to teach U-Boot about Allwinner's
newest SoC generation. This was introduced with the RISC-V based
Allwinner D1 SoC, which actually shares a die with the ARM cores versions
called R528 (BGA, without DRAM) and T113s (QFP, with embedded DRAM).

This adds the new Kconfig stanza, using the two newly introduced symbols
for the new SoC generation and pincontroller. It also adds the new symbols
to the relavent code places, to set all the hardcoded bits directly.

We need one DT override:
The ARM core version of the DT specifies the CPUX watchdog as
"reserved", which means it won't be recognised by U-Boot. Override this
in our generic sunxi-u-boot.dtsi, to let U-Boot pick up this watchdog,
so that the generic reset driver will work.

a94c9c809b sunxi: clock: support D1/R528 PLL6 clock
The PLL_PERIPH0 clock changed a bit in the D1/R528/T113s SoCs: there is
new P0 divider at bits [18:16], and the M divider is 1.

Add code to support this version of "PLL6".

39ba474698 sunxi: clock: D1/R528: Enable PLL LDO during PLL1 setup
The D1/R528/T113s SoCs introduce a new "LDO enable" bit in the CPUX_PLL.
Just enable that when we program that PLL.

4a9e89a3e3 sunxi: introduce NCAT2 generation model
Allwinner seems to typically stick to a common MMIO memory map for
several SoCs, but from time to time does some breaking changes, which
also introduce new generations of some peripherals. The last time this
happened with the H6, which apart from re-organising the base addresses
also changed the clock controller significantly. We added a
CONFIG_SUN50I_GEN_H6 symbol back then to mark SoCs sharing those traits.

Now the Allwinner D1 changes the memory map again, and also extends the
pincontroller, among other peripherals.
To mark this generation of SoCs, add a CONFIG_SUNXI_GEN_NCAT2 symbol,
this name is reportedly used in the Allwinner BSP code, and prevents us
from inventing our own name.

Add this new symbol to some guards that were already checking for the H6
generation, since many features are shared between the two (like the
renovated clock controller).

This paves the way to introduce a first user of this generation.

1da48c99de pinctrl: sunxi: move PIO_BASE into sunxi_gpio.h
On the Allwinner platform we were describing a quite comprehensive
memory map in a per-SoC header unser arch/arm.
In the old days that was used by every driver, but nowadays it should
only be needed by SPL drivers (not using the DT). Many addresses in
there were never used, and some are not needed anymore.

To avoid a dependency on CPU specific headers in an arch specific
directory, move the definition of the pinctroller MMIO base address into
the sunxi_gpio.h header, because the SPL routines for GPIO should be the
only one needing this address.
This is a first step towards getting rid of cpu_sun[x]i.h completely,
and allows to remove the inclusion of that file from the sunxi_gpio.h
header.

207ed0a3dd pinctrl: sunxi: remove GPIO_EXTRA_HEADER
U-Boot's generic GPIO_EXTRA_HEADER is a convenience symbol to allow code
to more easily include platform specific GPIO headers. This should not
be needed in a DM world anymore, since the generic GPIO framework
handles that nicely.
For Allwinner boards we still need to deal with non-DM GPIO in the SPL,
but this should become the exception, not the rule.

Make this more obvious by removing the definition of GPIO_EXTRA_HEADER,
and just force every legacy user of platform specific GPIO to include
the new sunxi_gpio.h header explicitly. Everyone doing so should feel
ashamed and should find a way to avoid it from now on.

30097ee3d2 pinctrl: sunxi: remove struct sunxi_gpio
So far every Allwinner SoC used the same basic pincontroller/GPIO
register frame, and just differed by the number of implemented banks and
pins, plus some special functionality from time to time. However the D1
and successors use a slightly different pinctrl register layout.
Use that opportunity to drop "struct sunxi_gpio", that described that
MMIO frame in a C struct. That approach is somewhat frowned upon in the
Linux world and rarely used there, though still popular with U-Boot.

Switching from a C struct to a "base address plus offset" approach allows
to switch between the two models more dynamically, without reverting to
preprocessor macros and #ifdef's.

Model the pinctrl MMIO register frame in the usual "base address +
offset" way, and replace a hard-to-parse CPP macro with a more readable
static function.
All the users get converted over. There are no functional changes at
this point, it just prepares the stages for the D1 and friends.
