2013-12-12ARM: footbridge: fix VGA initialisationRussell King
commit 43659222e7a0113912ed02f6b2231550b3e471ac upstream. It's no good setting vga_base after the VGA console has been initialised, because if we do that we get this: Unable to handle kernel paging request at virtual address 000b8000 pgd = c0004000 [000b8000] *pgd=07ffc831, *pte=00000000, *ppte=00000000 0Internal error: Oops: 5017 [#1] ARM Modules linked in: CPU: 0 PID: 0 Comm: swapper Not tainted 3.12.0+ #49 task: c03e2974 ti: c03d8000 task.ti: c03d8000 PC is at vgacon_startup+0x258/0x39c LR is at request_resource+0x10/0x1c pc : [<c01725d0>] lr : [<c0022b50>] psr: 60000053 sp : c03d9f68 ip : 000b8000 fp : c03d9f8c r10: 000055aa r9 : 4401a103 r8 : ffffaa55 r7 : c03e357c r6 : c051b460 r5 : 000000ff r4 : 000c0000 r3 : 000b8000 r2 : c03e0514 r1 : 00000000 r0 : c0304971 Flags: nZCv IRQs on FIQs off Mode SVC_32 ISA ARM Segment kernel which is an access to the 0xb8000 without the PCI offset required to make it work.

2010-02-15ARM: 5880/1: arm: use generic infrastructure for early paramsJeremy Kerr
The ARM setup code includes its own parser for early params, there's also one in the generic init code. This patch removes __early_init (and related code) from arch/arm/kernel/setup.c, and changes users to the generic early_init macro instead. The generic macro takes a char * argument, rather than char **, so we need to update the parser functions a little.

2009-01-08[ARM] footbridge: add isa_init_irq() to common headerBen Dooks
isa_init_irq() is defined in arch/arm/mach-footbridge/isa-irq.c and used in arch/arm/mach-footbridge/common.c but there is no definition in any header. Move the definition in common.c to common.h to stop the sparse warning: isa-irq.c:118:13: warning: symbol 'isa_init_irq' was not declared. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
