Subject: [PATCH v3 00/21] RISC-V: erizo: migrate to PBL
Date: Sun, 21 Mar 2021 16:13:23 +0100	[thread overview]
Message-ID: <20210321151344.5810-1-a.fatoum@pengutronix.de> (raw)

With these changes applied, barebox can now generate images that can
be booted on qemu/tinyemu virt32 and virt64 machines.

The boards have clocksource, virtio, cfi-flash,  reboot and poweroff
support.

This can also be pulled from Github:
https://github.com/a3f/barebox/tree/multi-image-riscv-v3

v2 -> v3:
 - reworded some commit titles
 - added new header format for barebox images
 - added filetype detection for new barebox image format
 - fixed use of uninitialized sp in Erizo ENTRY_POINT (Antony)
 - Replaced assembly entry point of generic DT image with customized
   version of new header format macro
 - early exit relocation if runtime offset == 0
 - remove note about TLSF error that's now fixed after Antony's bisection
 - replace 2 line assembly function in entry_ll.S with inline code

v1 -> v2:
 - moved compressed dtb helpers into common header for both ARM and
   RISC-V to use
 - relocate_to_adr(fixed_base) can now be called multiple times in a row
 - removed some extra spaces (Antony)
 - as arch is DT only, bumped pr_debug to pr_err if dt is not found.
   no panic, because with debug_ll you might still be able to boot to shell
   for further debugging
 - rename Makefile.erizo to Makefile.riscv. Let's just build all board images
   out of the same Makefile now
 - HAS_ARCH_SJLJ selected for 64-bit as well
 - don't require compiler to support atomics or floating point on rv64 (Rouven)
 - added RISCV timer for SBI and rdcycle mode. This is used on tinyemu virt.
   rdcycle mode could be used on erizo as well if suitable timerbase chosen.
 - activate first console because Tinyemu only describes virtio mmio region
   for console and no stdout-path

Cheers,
Ahmad Fatoum (19):
  partitions: don't allocate dma capable memory
  images: make BOARD_ARM_GENERIC_DT available for other arches
  ARM: make ARM_USE_COMPRESSED_DTB available for other arches
  ARM: aarch64: omit unused label in assembly
  serial: virtio-console: depend on, but don't select VIRTIO
  RISC-V: <asm/unaligned.h>: don't do unaligned accesses
  RISC-V: debug_ll: ns16550: align C access size with assembly's
  RISC-V: drop duplicate or unneeded cflags
  RISC-V: add cacheless HAS_DMA support
  RISC-V: erizo: move to arch/riscv/boards/erizo
  RISC-V: import Linux' optimized string functions
  filetype: detect RISC-V images
  RISC-V: implement PBL image header
  RISC-V: implement PBL and relocation support
  RISC-V: erizo: migrate to PBL
  RISC-V: support symbol names in barebox image
  RISC-V: add generic DT image
  clocksource: add driver for RISC-V and CLINT timers
  power: reset: add drivers for generic syscon reset and poweroff

Rouven Czerwinski (2):
  RISC-V: add 64-bit support
  RISC-V: add Qemu virt support
