We use i.mx 6solox as a pcie ep connected to a x86 board. On the x86 board, we can find 64k memory space used for
expansion rom in the pcie configuration space, offset 0x30. Here are my questions:
Q1: Is it useful or useless about the expansion rom space?
Q2: Is there any way to disable the rom space ? Not only clear the enable bit, but return all 0s after writing 0xFFFFFFFE to the PCIE_EP_EROMBAR field(Now a value of 0xFFFF0000 returns, that stands for 64KB).
Thanks very much!
