[Xen-devel] [PATCH] ioemu-remote&ioemu: fix flag for expansion rom base
This patch fixes flag for expansion rom base address register.
It can be applied to both ioemu-remote and ioemu.
pt_bar_reg_parse() is called for expansion rom base address register.
Currently it returns PT_BAR_FLAG_MEM if bit 0 is 0. It returns
PT_BAR_FLAG_IO if bit 0 is 1.
But bit 0 in expansion rom base address register is enable bit. If bit
0 is 1 for some reason, it returns PT_BAR_FLAG_IO. Expansion rom is
mapped to memory space. It should return PT_BAR_FLAG_MEM.
After applying this patch, it returns PT_BAR_FLAG_MEM regardless
of bit 0, when it is called for expansion rom base address register.
