[Qemu-devel] [PATCH] Incorrect MBAR offset for an5206 UART2 output port bit set

[Evan Goldenberg]

The MBAR offset for the UART2 output port bit set function on the
an5206 board, though unimplemented, is incorrectly defined as 0x1c8.
The correct offset used by the hardware for this function is 0x1b8.
This typo causes QEMU to crash whenever attempts to access use UART2
are made:

qemu: fatal: Bad MBAR write offset 0x1b8

The following patch resolves this issue.
