Subject: ARM: omap-common: Add device type to CPU string
X-Git-Tag: KARO-TXSD-2017-03-15~952
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=47c331ede1ef339425348cdc762e1feab6779d06;p=karo-tx-uboot.git

ARM: omap-common: Add device type to CPU string

Update the CPU string output so that the device
type is now included as part of the CPU string that
is printed as the SPL or u-boot comes up. This update
adds a suffix of the form "-GP" or "-HS" for production
devices, so that general purpose (GP) and high security
(HS) can be distiguished. Applies to all OMAP5 variants.
