arch/arm: fix-up the ARM Kconfig warning

2013-02-07T19:39:26+00:00

Kconfig does not accepts that a symbol that is part of a choice be affected a default value. Fix this by introducing a dummy EABI symbol, and make the real EABI symbol a prompt-less option that depends on !OABI. [Peter: drop arm dependency, rename to EABI_CHOICE] Signed-off-by: "Yann E. MORIN" Cc: Peter Korsgaard Cc: Arnout Vandecappelle Signed-off-by: Peter Korsgaard

arm: deprecate OABI

2013-02-07T07:44:05+00:00

The BR2_ARM_EABI config symbol is still kept in order to minimize the impact. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Peter Korsgaard

arch/Config.in.arm: Use armv6k for arm1136jf-s rev1

2013-02-02T07:28:22+00:00

According to the ARM1136JF-S and ARM1136J-S Revision r1p5 Technical Reference Manual, from release rev1 (r1pn), the ARM1136JF-S processor implements the ARMv6 instruction set with the ARMv6k additions. This patch differentiates the ARM1136JF-S revisions 0 and 1 in order to use either ARMv6j (e.g. on Freescale i.MX31) or ARMv6k (e.g. on Freescale i.MX35).

arch/sparc: drop old SUN-specific variants

2013-01-02T13:59:55+00:00

Drop the old Sun-specific variants used in old workstations (pre-1997) and other useless ones. The V7 ISA is a very old cpu only used in the first Sun workstations, the toolchain support is broken: the cpu doesn't do hardware div and it's not handled elsewhere. The sparclite is also a very old Fujitsu cpu only used in early 90s Sun machines (includes f930 & f934). The sparclet (tsc701) was a microcontroller-variant. The supersparc and hypersparc are just V8 variants also used in old Sun workstations/servers. Signed-off-by: Gustavo Zacarias Signed-off-by: Peter Korsgaard

arch/Config.in.arm: Add BR2_ARM_CPU_HAS_NEON similar to how mmx/sse is handled on x86

2012-12-13T22:25:53+00:00

NEON support is optional on A5/A9, so let the user choose if SoC has it / wants to use it. Signed-off-by: Peter Korsgaard

arm: update processor types

2012-12-09T22:07:11+00:00

Update the arm processor types: add the cortex A5 & A15 variants. Signed-off-by: Gustavo Zacarias Signed-off-by: Peter Korsgaard

powerpc: update processor types

2012-12-09T22:07:03+00:00

Update the powerpc processor types. Remove the 801, it's the original IBM experimental implementation. Add the 464, 464fp, 476 and 476fp cores. Signed-off-by: Gustavo Zacarias Signed-off-by: Peter Korsgaard

xtensa: use uppercase for configurations and modified overlay structure

2012-11-21T10:08:50+00:00

Except for architecture and processor names, buildroot uses capitalized configuration names, so change the macro names for xtensa to follow that standard. Change the overlay file to have a subdirectory for each component (gdb, binutils, gcc, etc.) to make it more future-prove. Signed-off-by: Chris Zankel Signed-off-by: Peter Korsgaard
