Build sparc32 openbios
by BALARD Arnaud
Hi, Openbios !
I try to build a bios sparc32 for qemu.
I use the script "./config/scripts/switch-arch sparc32"
Initializing build tree ok
Creating taget config.mak ok
Creating taget rules.mak ok
Creating config files ok
When I do the "make build-verbose" I get the following error :
"PATH/openbios/arch/sparc32/context.c: In function 'switch_to':
"PATH/openbios/arch/sparc32/context.c:116:5: error: PIC register clobbered by 'l7' in 'asm'
Asm_volatile_("\n\tcall_switch_context"
^~~
Rules.mak:219 « target/arch/sparc32/context.o » failed
Make[1]: *** [target/arch/sparc32/context.o error 1
Makefile:32 target "subdir-sparc32" failed
Make: *** [subdir-sparc32] error 2
I was try to build ppc and sparc64, that's ok, I can boot on my ppc's bios (not on sparc64, I think I need to do another thing).
Do you know what I'm doing wrong for sparc 32 ?
Thanks,

[PATCH v2 0/5] SPARC32/SPARC64: allocate and map both kernel and initrd memory
by Mark Cave-Ayland
Bootloaders such as SILO will have already allocated and mapped the memory for
the kernel and initrd before jumping into the kernel, so this patchset does the
same for a kernel/initrd loaded directly by QEMU.
Otherwise if the kernel/initrd grow beyond the default 1:1 memory region mapped
by the PROM then the kernel will panic when clearing the memory on startup.
In order for this to work on SPARC32 then the corresponding QEMU patch at
https://lists.gnu.org/archive/html/qemu-devel/2019-01/msg06635.html must also be
applied.

v2:
- Add missing PAGE_ALIGN() macro around the ofmem_map() size parameter
Mark Cave-Ayland (5):
SPARC32: fix obp_arg.argv when no kernel command line specified
SPARC32: mark kernel memory as mapped
SPARC32: mark initrd memory as mapped and in use before booting kernel
SPARC64: mark kernel memory as mapped and in use before booting kernel
SPARC64: mark initrd memory as mapped and in use before booting kernel
