- temp fix for boot hangup with camera
This reverts commit a8109598e7dca72d415ad5d26ac5868b88da9dfc.
Bug: 115532706
Test: test boot up
Change-Id: I7bb1bc14eb81ae0965fc03abdf5cb65444720d13
Add fastboot commands "fastboot oem at-get-vboot-unlock-challenge"
and "fastboot oem at-unlock-vboot" to support the authenticated
unlock feature for Android Things devices. Use software random
numbers generator to generate the 16 bytes random challenge, it
should be replaced with hardware encrypted random generator when
the TEE part is ready.
Test: Generate unlock challenge by:
./avbtool make_atx_unlock_credential
--output=atx_unlock_credential.bin
--intermediate_key_certificate=atx_pik_certificate.bin
--unlock_key_certificate=atx_puk_certificate.bin
--challenge=my_generated_challenge.bin
--unlock_key=testkey_atx_puk.pem
validated the unlock credential successfully on imx7d_pico
and AIY.

Trusty image should be loaded to different address for AIY 1G/3G ddr
board which have different ddr size. Use board id to distinguish
different baseboard, load trusty image to 0x7e00_0000 for AIY 1G ddr
board and 0xfe00_0000 for AIY 3G ddr board.
Test: build and boot Trusty ok for AIY 1G/3G ddr board.

MLK-19263-2 imx8mq_evk: Adjust SPL malloc pool and stack address
Currently the SRAM is allocated to malloc pool due to large malloc
needed by USB SDP. The stack is moved to OCRAM. This causes a
problem when enabling HAB. The HAB authentication needs large
memory on stack, so after ATF image loaded, the stack overwrites
the ATF image in OCRAM and causes authentication failed.
This patch moves the malloc pool to DDR and set back stack to
SRAM. So SDP still can run with enough memory on DDR. And the
stack overwrite issue can be fixed by enough memory 24KB left on
SRAM.
This change also need to use a early malloc pool by defining the
CONFIG_MALLOC_F_ADDR. And in SPL codes, we have to adjust DDR init
before board_init_r.

Sync configs with BSP team to enable uuu for imx8m AIY board,
create new file imx8mq_phanbell_androidthings_uuu_defconfig
for uuu image build.
Test: uuu works on imx8m AIY board.

Decrease the phanbell DDR(1G + 3G) frequency to 1600
MTS, this may save some power.
Test: Boot ok on both 1G and 3G DDR board, the dram_core_clk
decrease from 800000000 to 400000000.
