Hi,
analogously to x86, this series provides some platform information on
ARM via the communication region.
In sum, this series passes to inmates:
- A struct jailhouse_debug_console to inmates on all architectures
(including x86, but there it is not used yet)
- arm: GIC (v3 and v4) register locations
- arm: Platform Timer IRQ
The nice thing is that we get rid of mach.h on ARM architectures, which
makes inmates completely platform independant.
Inmate command line options (e.g., con-type, con-divider, ...) may still
override platform information.
Tested on a Jetson TK1 and qemu-arm64.
I converted this to a RFC series as there are still some things missing:
- Documentation for new comm region ABI
- Use the comm region's struct jailhouse_console on x86
- Analogously to arm: rewrite x86's uart drivers, embed them in struct
uart_chip
- We then can (probably) consolidate both architecture's printk.c

since v1:
- rebased to next
- register uart drivers in an array instead of a section: the section
approach won't work easily for our inmates
Ralf Ramsauer (18):
inmates: arm: uart: introduce DEFINE_UART macro
inmates: arm: uart: register uarts in uart_array
core, driver: rename struct jailhouse_console to jailhouse_ringbuf
core: refactor struct jailhouse_debug_console
inmates: arm: add consoles to inmate definition
core: pass cell's console to communication region
inmates: arm: configure uarts via communication region
core: add common platform info for ARM architectures
inmates: arm-common: define mmio_read64
inmates: arm: sysregs: define bits for MPIDR
inmates: arm: get GIC configuration from comm_region's platform info
inmates: arm: dynamically choose GIC version
core: arm: define timer_irq in sysconfig and pass it to comm_region
inmates: arm: use timer_irq from comm_region
inmates: arm: delete mach.h
core, tools: Increase header revision
core: increase comm_region's revision
inmates: arm: allow absence of config.h
