Hi,
Rev 2 of the series.
This is a follow up from [1] - Without the 32k crystal configuration,
wlan doesn't work. Debounce is needed for HDMI Hot plug detect(hpd)
gpio interrupt not storming.
At least the 32k configuration has been done for toradex and phytec
boards, follow similar model of programming.
Series is now based off master branch.
Bootlog: https://gist.github.com/nmenon/75df38bee907785d1d78d1ec4abd7304
Changes from V2:
- Removed depedency on [2] - depending on which way
the merge sequence goes, one of the series will need a rebase.
- Added a patch for a bug that Jan noticed
- Fixup for the fat finger missing 0x in 0x4080 :(

We had enabled USB and network pxe boot with the hope to get it all
merged on time. However, it has not panned out. Drop usb and pxe boot
else bootflow scan -l throws in:
a) Unknown uclass 'usb' in label
b) Crashes when attempting pxe - cpsw/mdio driver apparently has missing
error handling of what ever form. This is the one that Jan noticed in
his log.
We can enable these on a later date once things are working.

Enable the external 32k crystal similar to that found on other
production AM62X board. The trim settings for the crystal is board
dependent, so the sequences tend to be board specific. Since this is
a configuration that needs to be done prior to DM managing the system
and all other muxes get set, do the same from R5 context.

QEMU's -m option can take fractional megabyte values,
and lowest granularity seems to be 0x2000.
For example, run qemu with amount of memory set to 100005k (0x61A9400):
$ qemu-system-arm -machine virt -cpu cortex-a15 -m 100005k \
-bios denx/u-boot.bin -nographic
=> fdt addr $fdt_addr
=> fdt print /memory@40000000
memory@40000000 {
reg = <0x00000000 0x40000000 0x00000000 0x061aa000>;
device_type = "memory";
};
When LPAE is enabled, 1:1 mapping is created using 2 MB blocks.
In case amount of memory provided to QEMU is not multiple
of 2 MB, hang occurs during MMU initialization.

Heavily inspired by Apple board code. Use the LMB allocator to configure
load addresses at runtime, and implement a lookup table for selecting a
devicetree.
As some Qualcomm RBx boards have different RAM capacities and base
addresses, it isn't possible to hardcode these regions.

Historically, Qualcomm boards have relied on heavy hardcoding in U-Boot,
in many cases to the specific SoC but also to the board itself (e.g.
memory map). This has been largely resolved by modernising the Qualcomm
drivers in U-Boot, however the board code still largely follows this
model.
This patch removes the board specific memory maps and duplicated board
init code, replacing it with generic init code.
The memory map is now built at runtime based on data read from DT, this
allows for the memory map to be provided without having to recompile
U-Boot. Support is also added for booting with appended DTBs, so that
the first-stage bootloader can populate the memory map for us.
The sdm845 specific init code is dropped entirely, it set an environment
variable depending on if a button was pressed, but this variable wasn't
used in U-Boot, and could be written to use the button command instead.
The KASLR detection is also dropped as with appended dtb, the kaslr seed
can be read directly from the DTB passed to U-Boot.
A new qcom_defconfig is added, with the aim of providing a generic
U-Boot configuration that will work on as many Qualcomm boards as
possible. It replaces the defconfig files for the Dragonboard 845c,
Galaxy S9, and QCS404 EVB. For now the db410c and 820c are excluded as
they still have some board code left.
Similarly, the config headers for db845c, starqltechn, and qcs404-evb
are replaced by a single qcom header.
The previously db410c-specific board_usb_init() function is made to be
generic and is added to mach-snapdragon. While we lack proper modelling
for USB configuration, using a well-known named pinctrl state is a
reasonably generic middleground, and works using upstream DT. This
function will do nothing unless the USB node has a pinctrl state named
"device", in which case it will be set when entering USB peripheral
mode.

Some of the db410c board support code was written to be generic and
placed in mach-snapdragon. However, as the db410c is the only board
using this, move the code out of mach-snapdragon. This makes is more
obvious what code is relevant for which targets and helps tidy things up
a little more.

Generally speaking, we do not prompt for this value and define it in the
board specific Kconfig file. There are some valid use cases however
today where we do prompt for this value, so instead of having this be
done in a number of locations, do this at the top-level location only.
This removes the question from a number of other locations and makes it
consistent that when we do set the value directly, we always do it the
same way. We don't need to specify the type, it's always string.
