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:
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.
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.
