f6432ecea6 pico-imx6ul: Provide a way to escape the Falcon mode
When CONFIG_SPL_OS_BOOT is selected, it is still convenient to be able
to escape from Falcon mode and boot to U-Boot proper.

Add a mechanism that allows booting in U-Boot proper when the
key 'c' is entered on console at boot time.

831824c0a7 pico-imx6ul: Increase the CONFIG_ENV_OFFSET size
U-Boot binary has grown in such a way that it goes beyond the reserved
area for the environment variables.

Running "saveenv" causes U-Boot to hang because of this overlap.

Fix this problem by increasing the CONFIG_ENV_OFFSET size.

Also, in order to prevent this same problem in the future, use
CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap in build-time.

CONFIG_BOARD_SIZE_LIMIT does not accept math expressions, so declare
CONFIG_ENV_OFFSET with its direct value instead.

40af7d39aa habv4: tools: Avoid hardcoded CSF size for SPL targets
Currently it's not possible to authenticate the U-Boot proper of
mx6ul_14x14_evk_defconfig target:

Authenticate image from DDR location 0x877fffc0...
bad magic magic=0x0 length=0x00 version=0x3
bad length magic=0x0 length=0x00 version=0x3
bad version magic=0x0 length=0x00 version=0x3
spl: ERROR:  image authentication fail

Commit 0633e13478 ("imx: hab: Increase CSF_SIZE for i.MX6 and
i.MX7 devices") has increased CSF_SIZE to avoid a possible issue
when booting encrypted boot images.

Commit d21bd69b6e ("tools: mkimage: add firmware-ivt image type
for HAB verification") is hardcoding the CSF and IVT sizes, the
new CSF size is not being considered and u-boot-ivt.img fails to
boot.

Avoid hardcoded CSF and IVT size to fix this issue.

7171437166 imx6: spl: Reduce SPL limit size in case CONFIG_SECURE_BOOT is enabled
In case CONFIG_SECURE_BOOT is enabled we need to limit the SPL size to
avoid a possible HAB failure event:

--------- HAB Event 1 -----------------
event data:
        0xdb 0x00 0x14 0x42 0x33 0x22 0x33 0x00
        0x00 0x00 0x00 0x0f 0x00 0x90 0x70 0x00
        0x00 0x01 0x10 0x00
STS = HAB_FAILURE (0x33)
RSN = HAB_INV_ADDRESS (0x22)
CTX = HAB_CTX_TARGET (0x33)
ENG = HAB_ENG_ANY (0x00)

As explained in Commit 23612534fe ("spl: imx6: Provide a SPL_SIZE_LIMIT
default") the i.MX6 SPL size limit is 68KB.

The ROM code is copying the image size defined in boot data to its
respective load address, in case we exceed the OCRAM free region a
HAB invalid address failure event is generated.

The maximum CSF size is defined in CONFIG_CSF_SIZE, reduce SPL size
limit based on this configuration.

91457597e3 mx6sabresd: Reduce overall SPL size
Currently the SPL binary is 67 kB, which leaves only 1 kB of free

The following options can be safely removed to save some precious
SPL space:

- CONFIG_SPL_FS_EXT4: u-boot-dtb.img is stored in raw sector via dd
command (at offset 69 kB)
- CONFIG_SPL_I2C_SUPPORT: I2C is not used during SPL
- CONFIG_SPL_OS_BOOT: no need to make Falcon mode supported
by default

After this change the SPL binary size gets down to 51 kB.
