v4:
* Drop ARMv7MState to ARMMProfileState rename because it causes a lot of code
churn and is incomplete. Other parts of QEMU (like NVIC emulation) still
refer to "v7m" although they apply to other architecture versions too.
[Peter]
* Use the generic loader device (-device loader,file=program.hex,cpu-num=1)
instead of -kernel. -kernel is a legacy command-line option that is kept as
a convenience, but it's not as flexible or predictable as the generic loader
device. New image formats should be added to the generic loader device.
[Peter]
* Use hex/ASCII literals instead of decimal literals in hexloader-test.c.
This makes the test case slightly easier to understand. [Philippe]
v3:
* Rename ARMv7MState to ARMMProfileState so a single class can cater for
ARMv6-M, ARMv7-M, and ARMv8-M [Peter]
* Make bitbanding optional via a qdev property [Peter]
* Add hex file loader patches to reduce dependencies in upcoming patch series
* Implement rollback if hex file loader fails partway through [Peter]
* Update hex file loader test case to use an ARMv7-M board since hex file
loading is only done for ARM M Profile boards
This series contains the prerequistes for the "microbit" machine type that Joel
Stanley has written. I have combined the Cortex M0 CPU model and hex loader
work into one series to reduce the dependencies in upcoming patch series from
Joel, Julia, and Steffen.
This patch series:
* Makes bitbanding optional on ARMv7MState.
* Adds a "cortex-m0" cpu type which can be used with ARMMProfileState. This
works thanks to Julia's Cortex M0 emulation patches, which are now all
merged.
* Adds Su Hang's Intel HEX file format loader so that micro:bit and other
microcontroller firmware images can be run using -kernel. The micro:bit
development tools typically only emit .hex files and not ELFs.
Stefan Hajnoczi (4):
hw/arm: make bitbanded IO optional on ARMv7-M
target/arm: add "cortex-m0" CPU model
loader: extract rom_free() function
loader: add rom transaction API
Su Hang (2):
loader: Implement .hex file loader
Add QTest testcase for the Intel Hexadecimal
