Update the distro config env memory layout for the Apalis iMX8 aka
QuadMax:
- kernel_comp_addr_r=0xf0000000 temporary area for uncompressing (ie FIT
images or Image.gz booted using booti)
- kernel_comp_size=0x08000000
- loadaddr=0x95400000 avoiding any reserved areas located before that
- fdt_addr_r = loadaddr + 128MB - allows for 128MB kernel
- scriptaddr = fdt_addr_r + 512KB - allows for 512KB fdt
- ramdisk_addr_r = scriptaddr + 512KB - allows for 512KB script
Basic idea of memory layout taken from commit fd5c7173ad
("imx8m{m,n}_venice: update env memory layout"). However, moved past
any reserved areas to avoid any kind of conflicts.
Note that for our regular BSP Layers and Reference Images for Yocto
Project an updated distro boot script is required (see
meta-toradex-bsp-common/recipes-bsp/u-boot/u-boot-distro-boot).
