> We now have EFI support in U-Boot which worked out of the box on all
> systems that I tried it on so far. Except for the LS2080ARDB. With this patch
> set I can successfully boot grub2 and Linux from there on such a system -

> v3 -> v4:
> 
>   - Add CONFIG_CMD_FS_GENERIC to defconfig
>   - Move code into generic quiesce weak function
>   - Exit device for real when going to Linux
>   - Only apply DPL if we have something to apply
>   - New: armv8: ls2080a: Declare spin tables as reserved for efi loader
>   - New: efi_loader: Allow boards to implement get_time and reset_system
>   - New: armv8: fsl-layerscape: Add support for efi_loader RTS reset
>   - New: efi_loader: Declare secure memory as reserved
>   - New: efi_loader: Allow bouncing for network
> 
> Alexander Graf (9):
>   ls2080: Exit dpaa only right before exiting U-Boot
>   efi_loader: AArch64: Run EFI payloads in EL2 if U-Boot runs in EL3
>   ls2080ardb: Reserve DP-DDR RAM
>   ls2080ardb: Convert to distro boot
>   armv8: ls2080a: Declare spin tables as reserved for efi loader

I am testing your patch set on ls2080ardb. 
Observation:-
1. Linux boot no more crashing with e1000#0, DPMAC5 at XSGMII. Even tried with default bootcmd. 
2. Grub2 crash while booting :(

I have applied your patch on top of commit " 9f823615af919c6b89f0b80197f009f78299dcde"
