Adding support for AM43xx secure devices require the addition of some SOC specific config options like the amount of memory used by public ROM and the address of the entry point of u-boot or SPL, as seen by the ROM code, for the image to be built correctly. This mandates the addition of am AM43xx CONFIG option and the ARM Kconfig file has been modified to source this SOC Kconfig file. Moving the TARGET_AM43XX_EVM config option to the SOC KConfig and out of the arch/arm/Kconfig. Updating defconfigs to add the CONFIG_AM43XX=y statement and removing the #define CONFIG_AM43XX from the header file.

After any reset, the boot ROM on the AM43XX SOC
|
|
searches the boot media for a valid boot image.
|
|
For non-XIP devices, the ROM then copies the
|
|
image into internal memory.
|
|
For all boot modes, after the ROM processes the
|
|
boot image it eventually computes the entry
|
|
point address depending on the device type
|
|
(secure/non-secure), boot media (xip/non-xip) and
|
|
image headers.

help
|
|
During the device boot, the public ROM uses the top of
|
|
the public L3 OCMC RAM to store r/w data like stack,
|
|
heap, globals etc. When the ROM is copying the boot
|
|
image from the boot media into memory, the image must
|
|
not spill over into this area. This value can be used
|
|
during compile time to determine the maximum size of a
|
|
boot image. Once the ROM transfers control to the boot
|
|
image, this area is no longer used, and can be reclaimed
|
|
for run time use by the boot image.
