ubifs_iget() returns error codes encoded in the pointer,

arm: cpu: add basic arm64 mmu support ...

This commit adds basic mmu support, ie:
        - DMA cache handling is not supported
        - Remapping memory region also

The current mmu setting is:
        - 4KB granularity
        - 3 level lookup (skipping L0)
        - 33 bits per VA

This is based on coreboot and u-boot mmu configuration.

ARM: bootm: recalculate decompression space ...

According to the kernel documentation it is recommended to place the
compressed image between 32 MiB and 128 MiB. The DTB and initrd should
be placed above 128 MiB. We will follow the recommendation as long as we
have enough RAM. If this is not the case, we fall back to the scheme.
This change is required because of the ARM default kernel config changes
regarding RODATA layout, which lead to an increased compression factor
of the kernel image.
This should be regarded as an intermediate solution until there is a
mechanism for the kernel image to report the decompressed layout
requirements to the bootloader.
