2021-08-24ARC: mm: move mmu/cache externs out to setup.hVineet Gupta1-2/+10
Don't pollute mmu.h and cache.h with ARC internal bootlog/setup related functions. Move them aside to setup.h Signed-off-by: Vineet Gupta <vgupta@kernel.org>
2020-10-05ARC: [plat-eznps]: Drop support for EZChip NPS platformVineet Gupta1-4/+0
NPS customers are no longer doing active development, as evident from rand config build failures reported in recent times, so drop support for NPS platform. Tested-by: kernel test robot <lkp@intel.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

2017-01-18ARCv2: IOC: Use actual memory size to setup aperture sizeVineet Gupta1-0/+1
vs. fixed 512M before. But this still assumes that all of memory is under IOC which may not be true for the SoC. Improve that later when this becomes a real issue, by specifying this from DT. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2016-10-28ARC: boot log: refactor cpu name/release printingVineet Gupta1-5/+0
The motivation is to identify ARC750 vs. ARC770 (we currently print generic "ARC700"). A given ARC700 release could be 750 or 770, with same ARCNUM (or family identifier which is unfortunate). The existing arc_cpu_tbl[] kept a single concatenated string for core name and release which thus doesn't work for 750 vs. 770 identification. So split this into 2 tables, one with core names and other with release. And while we are at it, get rid of the range checking for family numbers. We just document the known to exist cores running Linux and ditch others. With this in place, we add detection of ARC750 which is - cores 0x33 and before - cores 0x34 and later with MMUv2 Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2016-10-28ARCv2: boot log: print IOC exists as well as enabled statusVineet Gupta1-0/+1
Previously we would not print the case when IOC existed but was not enabled. And while at it, reduce one line off boot printing by consolidating the Peripheral address space and IO-Coherency which in a way applies to them Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2016-05-09ARC: [plat-eznps] Use dedicated COMMAND_LINE_SIZENoam Camus1-0/+4
The default 256 bytes sometimes is just not enough. We usually provide earlycon=... and console=... and ip=... All this and more may need more room. Signed-off-by: Noam Camus <noamc@ezchip.com> Acked-by: Vineet Gupta <vgupta@synopsys.com>

* No active users of this flag anymore * flag itself was no longer usable with new simualtor which acts just like hardware, not providing the special chip-id = 0xffff which good old ISS used to do. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2013-11-06arc: remove '__init' for setup_processor() and arc_init_IRQ()Chen Gang1-1/+1
They haven't '__init' in definition, but has '__init' in declaration. And normal function start_kernel_secondary() may call setup_processor() which will call arc_init_IRQ(). So need remove '__init' for both of them. The related warning (with allmodconfig): MODPOST vmlinux.o WARNING: vmlinux.o(.text+0x3084): Section mismatch in reference from the function start_kernel_secondary() to the function .init.text:setup_processor() The function start_kernel_secondary() references the function __init setup_processor(). This is often because start_kernel_secondary lacks a __init annotation or the annotation of setup_processor is wrong. Signed-off-by: Chen Gang <gang.chen@asianux.com>
