From: Ian Munsie <redacted> An issue was noted in our debug logs where the XSL would leave the RA bit asserted after an AFU reset operation, which would effectively prevent further AFU reset operations from working. Workaround the issue by clearing the RA bit with an MMIO write if it is still asserted after any AFU control operation. Signed-off-by: Ian Munsie <redacted>
OK, should be safe and valid even on non-xsl hardware. Reviewed-by: Frederic Barrat <redacted> Fred
