environment: ti: mmc_android: relocate U-Boot environment
The U-Boot environment is stored at offset 0x680000 (6.5MB)
While this is fine for AM62x SK EVM (because its mmc0boot0 partition is 31.5MB),
this does won't work on the Beagle Play, which only has 4MB.
Booting Beagle Play shows:
Loading Environment from MMC... MMC: block number 0x3500 exceeds max(0x2000)
*** Warning - !read failed, using default environment
Move the U-boot environment at lba 0x800 on mmc0boot0.
This reserves 1MB so that tiboot3 to be on mmc0boot0 as well, which is the
case for BeaglePlay.
Also add a raw_partition label so that we can erase it with:
fastboot erase bootenv
The boot0 partition now looks as:
blk
boot0 partition (31.5 MB)
0x0+----------------------------------+
| empty (1 MB) |
0x800+----------------------------------+
| environment (128 KB) |
| padding (384 KB) |
0xc00+----------------------------------+
| |
| Remaining space (30.0 MB) |
0xfc00+----------------------------------+
pick
Note:
CONFIG_ENV_OFFSET is in bytes and fastboot_raw_* is in lba number.
CONFIG_ENV_OFFSET=0x100000 -> lba 0x800
env size + padding = 512KB -> length of 0x400 lbas
