When booting Android with adtbo_idx set, we observe the
following crash:
** Booting bootflow 'mmc@fa10000.bootdev.whole' with android
## Booting Android Image at 0x82000000 ...
Kernel load addr 0x92000000 size 20195 KiB

x4 : 0000000002800000 x5 : 0000000000000020
This happens because the memory at fdtoverlay_addr_r is bogus.
In fact:
=> printenv fdtoverlay_addr_r
fdtoverlay_addr_r=0x89000000
And the ramdisk address range is:
[0x88080000; 0x88080000 + 16901 KiB]
Which is equal to:
[0x88080000; 0x89101400]
So, if we represent the addresses:
fdtaddr 0x88000000
ramdisk 0x88080000
fdtoverlay_addr_r 0x89000000
ramisk (end) 0x89101400
We see that fdtoverlay_addr_r in fact has been overridden by
the Android ramdisk.
The maximum ramdisk size is 0x1080000 (15,5 MiB) and a compressed
Android vendor ramdisk is 15MiB:
$ file vendor_ramdisk.img
vendor_ramdisk.img: LZ4 compressed data (v0.1-v0.9)
$ du -sh vendor_ramdisk.img
15M vendor_ramdisk.img
When it gets decompressed, it uses 16.5MiB, exceeding the
maximum ramdisk size.
Increase the maximum ramdisk size to 20.5MiB by moving
fdtoverlay_addr_r higher up in the address space to fix the crash.
