Here is the place it consumes too much time. Here is an example on a
warp7 board:

U-Boot 2021.07-rc3 (Jun 17 2021 - 18:30:37 +0000)

CPU:   Freescale i.MX7S rev1.2 800 MHz (running at 792 MHz)
CPU:   Extended Commercial temperature grade (-20C to 105C) at 42C
Reset cause: POR
Model: Warp i.MX7 Board
Board: WARP7 in secure mode OPTEE DRAM 0x9d000000-0xa0000000
DRAM:  464 MiB
PMIC: PFUZE3000 DEV_ID=0x30 REV_ID=0x11
Loading Environment from MMC... (takes 10 seconds to continue) OK

Can we go with the revert to avoid such regression?
