verdin-am62: fix FASTBOOT_BUF_ADDR and FASTBOOT_BUF_SIZE
The current value of CONFIG_FASTBOOT_BUF_ADDR is incorrect for hardware
with 512MB and 1GB of RAM. The RAM address ranges for these devices are:
- 512MB:
- Start: 0x80000000
- End: 0xA0000000
- 1GB:
- Start: 0x80000000
- End: 0xC0000000
The current buffer address makes fastboot downloads work only on
hardware with 2GB of RAM.
To fix this issue:
1. Lower CONFIG_FASTBOOT_BUF_ADDR to 0x88200000. This makes the buffer
to be equal ot CONFIG_SYS_LOAD_ADDR, which is a safe address to
download files using fastboot.
2. Reduce the size of the download buffer to 128MB, avoiding overlaps
with RAMDISK_ADDR_R. This is a good enough value for individual
downloads.
These changes make fastboot downloads work with 512MB and 1GB devices.
