Subject: GENIO: mt8195: boot order: SD -> UFS -> eMMC -> USB -> Network
|
|
|
|
Quality of life improvement for users who want to try different OS's
|
|
using SD card. With this change, once u-boot is loaded (from BootRoM
|
|
to UFS, always), it will try to boot an OS in the following order:
|
|
|
|
SD -> SCSI 2 (UFS) -> eMMC -> USB -> PXE(pxelinux) -> DHCP (PXE-EFI)
|
|
|
|
Of course, if board in question doesn't have an eMMC, it won't boot
|
|
from there, and that's the most common case on mt8195. It could be
|
|
argued that USB should boot after SD, but that causes an USB scan
|
|
that is slow and seems prone to failure currently.
|
|
|
|
Network already works on mt8195, so add it to the end of the boot
|
|
order. For it to actually work, one needs to set a MAC address in
|
|
the u-boot environment, and save it (it will be stored on UFS LUN 1).
|
|
The kernel will also use the same MAC.
|
|
in-uboot prompt: `setenv ethaddr xx:...` and `saveenv`
|
|
in-kernel: use `fw_setenv` if available
