So far for the H3, A23, and A33 SoCs, we use DRAM to hold the secure
monitor code (providing PSCI runtime services). And while those SoCs do
not have the secure SRAM B like older SoCs, there is enough (secure)
SRAM A2 to put the monitor code and data in there instead.
Follow the design of 64-bit SoCs and use the first part for the monitor,
and the last 16 KiB for the SCP firmware. With this change, the monitor
no longer needs to reserve a region in DRAM.

The PWM pins on North Bridge on Armada 37xx can be configured into PWM
or GPIO functions. When in PWM function, each pin can also be configured
to drive low on 0 and tri-state on 1 (LED mode).
The current definitions handle this by declaring two pin groups for each
pin:
- group "pwmN" with functions "pwm" and "gpio"
- group "ledN_od" ("od" for open drain) with functions "led" and "gpio"
This is semantically incorrect. The correct definition for each pin
should be one group with three functions: "pwm", "led" and "gpio".
Change the "pwmN" groups to support "led" function.
Remove "ledN_od" groups. This cannot break backwards compatibility with
older device trees: no device tree uses it since there is no PWM driver
for this SOC yet. Also "ledN_od" groups are not even documented.

This padding depends on board config file and therefore it makes the
mkimage binary tool board specific, which is not correct. One cannot use
mkimage tool built as a result for board A to generate images for board
B, even if both A and B are on the same platform.
This CONFIG_SYS_U_BOOT_OFFS padding was needed when kwbimage v1 contained
SPL code which loaded U-Boot proper based on CONFIG_SYS_U_BOOT_OFFS,
instead of reading correct offset from kwbimage header.
Now that SPL code parses kwbimage header and deterinate correct offset,
there is no need for this CONFIG_SYS_U_BOOT_OFFS padding anymore.
By removing it we also reduce the size of SPL code and therefore also
decrease the final size of v1 kwbimage. This means there is more space

Now that proper load and execution addresses are set in v1 kwbimage we
can use it for loading and booting U-Boot proper.
Use the new spl_parse_board_header() function to implement parsing the
kwbimage v1 header. Use information from this header to locate offset and
size of the U-Boot proper binary, instead of using the legacy U-Boot
header which is prepended to the U-Boot proper binary stored at fixed
offset. This has the advantage that we do not need to relay on legacy
U-Boot header anymore and therefore U-Boot proper binary can be stored at
any offset, as is the case when loading & booting U-Boot proper by
BootROM. The CONFIG_SYS_U_BOOT_OFFS option is therefore not used by SPL
code anymore.
Also allow to compile U-Boot SPL without CONFIG_SPL_SPI_FLASH_SUPPORT,
CONFIG_SPL_MMC_SUPPORT or CONFIG_SPL_SATA_SUPPORT set. In this case
BootROM is used for loading and executing U-Boot proper. This reduces the
size of U-Boot's SPL image. By default these config options are enabled
and so BootROM loading is not used. In some cases BootROM reads from SPI
NOR at lower speed than U-Boot SPL. So people can decide whether they
want to have smaller SPL binary at the cost of slower boot.
Therefore dependency on CONFIG_SPL_DM_SPI, CONFIG_SPL_SPI_FLASH_SUPPORT,
CONFIG_SPL_SPI_LOAD, CONFIG_SPL_SPI_SUPPORT, CONFIG_SPL_DM_GPIO,
CONFIG_SPL_DM_MMC, CONFIG_SPL_GPIO_SUPPORT, CONFIG_SPL_LIBDISK_SUPPORT,
CONFIG_SPL_MMC_SUPPORT, CONFIG_SPL_SATA_SUPPORT and
CONFIG_SPL_LIBDISK_SUPPORT is changed from strict to related "imply"
(which can be selectivelly turned off and causes booting via BootROM).
Options CONFIG_SYS_SPI_U_BOOT_OFFS,
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR and
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_DATA_PART_OFFSET have to to be set to
zero as they define the location where kwbimage header starts. It is the
location where BootROM expects start of the kwbimage from which it reads,
parses and executes SPL part. The same applies to option
CONFIG_SPL_SATA_RAW_U_BOOT_SECTOR, which has to be set to one.
Update all config files to set correct values of these options and set
CONFIG_SYS_U_BOOT_OFFS to the correct value - the offset where U-Boot
