In clock_sun8i_a83t.c, responsible for (mostly early) clock setup on the
Allwinner A83T SoC, many functions are only needed by the SPL, and are
thus already guarded by CONFIG_SPL_BUILD.
Over the years drivers like for the UART or I2C were converted to DM,
so they care about clock setup themselves now, by using a proper DM clock
driver.
This means those devices need the clock setup functions here for the SPL

so they are compiled for the SPL only.
This avoids unnecessary code in U-Boot proper and helps further

With the clock_twi_onoff() function now being called only from the SPL,
the whole clock.c file in arch/arm/mach-sunxi is needed by SPL code
only.
Remove the redundant #ifdef from the clock_init() function, actually
this function was already only called from the SPL.
Then adjust the Makefile to compile clock.c only with CONFIG_SPL_BUILD

At the moment this is guarded in board.c by some #ifdefs selecting the

R528/T113 SoCs uses the same SPI IP as the H6, also have the same clocks
and reset bits layout, but the CCU base is different. Another difference
is that the new SoCs do not have a clock divider inside. Instead of this
we should configure sample mode depending on input clock rate.
The pin assignment is also different: the H6 uses PC0, the R528/T113 PC4
instead. This makes for a change in spi0_pinmux_setup() routine.
This patch extends the H6/H616 #ifdef guards to also cover the R528/T113,
using the shared CONFIG_SUNXI_GEN_NCAT2 and CONFIG_MACH_SUN8I_R528
symbols. Also use CONFIG_SUNXI_GEN_NCAT2 symbol for the Kconfig
dependency.

In Linux, we allow sleep moci to be turned off when the carrier board
supports it and the system is in suspend. In U-Boot, however, we want
the sleep moci to be always on. So we use a gpio hog and disable the
regulator. This change is necessary because we switched to upstream
device tree files with commit 23fe2def1edf
("verdin-imx8mm/verdin-imx8mp: move imx verdins to OF_UPSTREAM"). A
recent upstream patch removes the gpio hog from the Linux device tree,
so we need to add it to the u-boot dtsi. The following patch will remove
the gpio hog from the Linux device tree:

In case of an OTP-CLOSED STM32MP15xx system, the CPU core 1 cannot be
released from endless loop in BootROM only by populating TAMP BKPxR 4
and 5 with magic and branch address and sending SGI0 interrupt from
core 0 to core 1 twice. TAMP_SMCR BKP..PROT fields must be initialized
as well to release the core 1 from endless loop during the second SGI0
handling on core 1. Initialize TAMP_SMCR to protect the first 32 backup
registers, the ones which contain the core 1 magic, branch address and
boot information.
This requirement seems to be undocumented, therefore it was necessary
to trace and analyze the STM32MP15xx BootROM using OpenOCD and objdump.
Ultimately, it turns out that a certain BootROM function reads out the
TAMP_SMCR register and tests whether the BKP..PROT fields are non-zero.
If they are zero, the BootROM code again waits for SGI0 using WFI, else
the execution moves forward until it reaches handoff to the TAMP BKPxR 5
branch address.
This fixes CPU core 1 release using U-Boot PSCI implementation on an
OTP-CLOSED system, i.e. system with fuse 0 bit 6 set.
