[Qemu-devel] [PATCH v2 11/15] imx_fec: Reserve full FSL_IMX25_FEC_SIZE page for the register file

[Andrey Smirnov]

Some i.MX SoCs (e.g. i.MX7) have FEC registers going as far as offset
0x614, so to avoid getting aborts when accessing those on QEMU, extend
the register file to cover FSL_IMX25_FEC_SIZE(16K) of address space
instead of just 1K.
