[Qemu-devel] [PATCH 01/13] mxs/imx23: Add main header file

[Michel Pollet <buserror@gmail.com>]

Header file containing most of the base addresses and IO registers
needed for the Freescale mxs/imx23 SoC emumation.
Also contains a generic helper to implement the SET/AND/OR/XOR trick
shared by pretty much all of the IO blocks on this SoC
