First target-arm pullreq of the 4.0 series; most of this is Mao's cleanups that finally let us drop sysbus::init; the most interesting user-visible feature is RTH's patches adding some v8.1 and v8.2 architecture features. thanks -- PMM The following changes since commit 6145a6d84b3bf0f25935b88543febe076c61b0f4: Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20181212' into staging (2018-12-13 13:06:09 +0000) are available in the Git repository at: https://git.linaro.org/people/pmaydell/qemu-arm.git tags/pull-target-arm-20181213 for you to fetch changes up to 2d7137c10fafefe40a0a049ff8a7bd78b66e661f: target/arm: Implement the ARMv8.1-LOR extension (2018-12-13 14:41:24 +0000) ---------------------------------------------------------------- target-arm queue: * Convert various devices from sysbus init to instance_init * Remove the now unused sysbus init support entirely * Allow AArch64 processors to boot from a kernel placed over 4GB * hw: arm: musicpal: drop TYPE_WM8750 in object_property_set_link() * versal: minor fixes to virtio-mmio instantation * arm: Implement the ARMv8.1-HPD extension * arm: Implement the ARMv8.2-AA32HPD extension * arm: Implement the ARMv8.1-LOR extension (as the trivial "no limited ordering regions provided" minimum) ---------------------------------------------------------------- Edgar E.

This eliminates the need for read-modify-update instruction sequences. This patch makes this optional feature an ARMv7MState qdev property, allowing boards to choose whether they want bitbanding or not. Status of boards: * iotkit (Cortex M33), no bitband * mps2 (Cortex M3), bitband * msf2 (Cortex M3), bitband * stellaris (Cortex M3), bitband * stm32f205 (Cortex M3), bitband As a side-effect of this patch, Peter Maydell noted that the Ethernet controller on mps2 board is now accessible. Previously they were hidden by the bitband region (which does not exist on the real board).

This is not quite correct. According to the i.MX7d referemce manual, Rev 0.1, §10.1.7.3: This bit [XCH] is cleared automatically when all data in the TXFIFO and the shift register has been shifted out. So XCH should be cleared when the FIFO empties, not on completion of a burst. The FIFO is 64 x 32 bits = 2048 bits, while the max burst size is larger at 4096 bits. So it's possible that the burst is not finished after the TXFIFO empties. Sending a large block (> 2048 bits) with the Linux driver will use a burst that is larger than the TXFIFO. After the TXFIFO has emptied XCH does not become unset, as the burst is not yet finished. What should happen after the TXFIFO empties is the driver will refill it and set XCH. The rising edge of XCH will trigger another transfer to begin. However, since the emulation does not set XCH to 0, there is no rising edge and the next trasfer never begins.
