43ec24be9b configs: lx2160a: Remove unused Flexspi config options
It is now safe to remove Flexspi configs NXP_FSPI_FLASH_SIZE and
NXP_FSPI_FLASH_NUM options from headers as they are no longer used by
driver anymore.

2dbcc037cc arm: socfpga: Only do 'is OS booted from FIT' checking when VAB is enabled
Check CONFIG_SOCFPGA_SECURE_VAB_AUTH before perform 'is OS booted from FIT'
checking in board_prep_linux function. And, fix typo of
CONFIG_SOCFPGA_SECURE_VAB_AUTH_ALLOW_NON_FIT_IMAGE.

CONFIG_FIT will be enabled in both ATF and VAB boot flow, thus,
board_prep_linux function will always be called by both ATF and
VAB boot flow.

board_pre_linux function will do 'is OS booted from FIT' checking,
and it will be called before board_fit_image_post_process function.

VAB boot flow expects the OS is always booted from FIT and with VAB
signed cerfiticate because the VAB authentication is implemented in
board_fit_image_post_process function. So, VAB needs the 'is OS booted
from FIT' checking in board_pre_linux function.

However, for ATF boot flow, it is not a requirement that the OS must
always booted from FIT. The OS can be booted from individual Image and
kernel dtb file. Thus, we should not do 'if OS is booted from FIT'
checking in board_prep_linux function.

bbfb81c187 ARM: mach-at91: arm926ejs: fix data abort in startup returning from lowlevel_init
The startup code in arm/cpu/arm926ejs preserves the link register across
the call to lowlevel_init by using r4:

mov	r4, lr		/* perserve link reg across call */
bl	lowlevel_init	/* go setup pll,mux,memory */
mov	lr, r4		/* restore link */

The lowlevel_init function for at91 machines based on the same CPU uses r4
and hence corrupts it causing a data abort when it returns to the startup
code. This patch fixes this by using r6 instead of r4 in the lowlevel_init
function.

Discovered and the fix was tested on a AT91SAM9261 based board.

The module defines a duplicate uclass driver for UCLASS_SIMPLE_BUS, but
it is not allowed. This breaks of-platdata and makes the result
non-deterministic.

The driver does not need to be an uclass driver, so lets remove it. I
had turned it into an uclass driver because I thought wrongly it had to
call the dm_scan_fdt_dev routine to work properly, but some tests on the

735ddfc638 dtoc: Support headers needed for drivers
Typically dtoc can detect the header file needed for a driver by looking
for the structs that it uses. For example, if a driver as a .priv_auto
that uses 'struct serial_priv', then dtoc can search header files for the
definition of that struct and use the file.

In some cases, enums are used in drivers, typically with the .data field
of struct udevice_id. Since dtoc does not support searching for these,
add a way to tell dtoc which header to use. This works as a macro included
in the driver definition.

b00f0066e5 dtoc: Support tracking the phase of U-Boot
U-Boot operates in several phases, typically TPL, SPL and U-Boot proper.
The latter does not use dtoc.

In some rare cases different drivers are used for two phases. For example,
in TPL it may not be necessary to use the full PCI subsystem, so a simple
driver can be used instead.

This works in the build system simply by compiling in one driver or the
other (e.g. PCI driver + uclass for SPL; simple_bus for TPL). But dtoc has
no way of knowing which code is compiled in for which phase, since it does
not inspect Makefiles or dependency graphs.

So to make this work for dtoc, we need to be able to explicitly mark
drivers with their phase. This is done by adding an empty macro to the
driver. Add support for this in dtoc.
