[PATCH v2] hw/char/pl011: Add support for loopback

is observed in real pl011 hardware placed in loopback mode: 1. Input characters and BREAK events from serial backend are ignored, but 2. Both TX characters and BREAK events are still sent to serial backend, in addition to be looped back to RX. Signed-off-by: Tong Ho Signed-off-by: Francisco

[PATCH] hw/char/pl011: Add support for loopback

This patch adds loopback for sent characters as well as modem-control signals. Loopback of send and modem-control is often used for uart self tests in real hardware but missing from current pl011 model, resulting in self-test failures when running in QEMU. Signed-off-by: Tong Ho Signed-off-by

[PATCH] hw/nvram: Avoid unnecessary Xilinx eFuse backstore write

Add a check in the bit-set operation to write the backstore only if the affected bit is 0 before. With this in place, there will be no need for callers to do the checking in order to avoid unnecessary writes. Signed-off-by: Tong Ho --- hw/nvram/xlnx-efuse.c | 11 +-- 1 file changed, 9
