I see Jagan posted patches for SPI flash booting, and the layout is
different from MMC.

Can we use the same layout here, ie: by reserving spaces for the
U-Boot environment on MMC?

See http://patchwork.ozlabs.org/project/uboot/patch/20200519192340.16624-7-jagan@amarulasolutions.com/

    0 - 34 : reserved for GPT header
   35 - 39 : unused
   40 - 2087 : loader1 (SPL, FSBL)
 2088 - 10279 : loader2 (U-Boot proper, U-Boot)
10280 - 10535 : environment
10536 - 65494 : rootfs
65528 - 65536 : distro script
