[U-Boot] [PATCH 0/2] ARM: mmu: Set domain permissions to client access

[R Sricharan]

Currently for ARM based cpu's, mmu pagetable attributes are set with
manager permissions for all 4GB address space. Because of this the
'execute never (XN)' permission is never checked on read sensitive
regions which results in speculative aborts.

This series changes the domain permissions of the full 4GB space
to client access for OMAP socs. This avoids all the speculative
aborts that are currently seen on OMAP5 secure devices.

Tested on OMAP5 SDP (HS) soc.

This series depends on [1] the patch sent by
