2017-04-11ARCv2: SLC: Make sure busy bit is set properly on SLC flushingAlexey Brodkin
As reported in STAR 9001165532, an SLC control reg read (for checking busy state) right after SLC invalidate command may incorrectly return NOT busy causing software to NOT spin-wait while operation is underway. (and for some reason this only happens if L1 cache is also disabled - as required by IOC programming model) Suggested workaround is to do an additional Control Reg read, which ensures the 2nd read gets the right status. Same fix made in Linux kernel: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c70c473396cbdec1168a6eff60e13029c0916854 Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

Even though we expect only master core to execute U-Boot code let's make sure even if for some reason slave cores attempt to execute U-Boot in parallel with master they get halted very early. If platform wants it may kick-start slave cores before passing control to say Linux kernel or any other application that want to see all cores of SMP SoC up and running.

2017-03-24arc: use timer driver for ARC boardsVlad Zakharov
This commit replaces legacy timer code with usage of arc timer driver. It removes arch/arc/lib/time.c file and selects CONFIG_CLK, CONFIG_TIMER and CONFIG_ARC_TIMER options for all ARC boards by default. Therefore we remove CONFIG_CLK option from less common axs101 and axs103 defconfigs. Also it removes legacy CONFIG_SYS_TIMER_RATE config symbol from axs10x.h, tb100.h and nsim.h configs files as it is no longer required.

2017-03-24arc: dts: separate single axs10x.dts fileVlad Zakharov
We want to use the same device tree blobs in both Linux and U-Boot for ARC boards. Earlier device tree sources in U-Boot were very simplified and hadn't been updated for quite a long period of time. So this commit is the first step on the road to unified device tree blobs. First of all we re-organize device tree sources for AXS10X boards. As AXS101 and AXS103 boards consist of AXS10X motherboard and AXC001 and AXC003 cpu tiles respectively we add corresponding device tree source files: axs10x_mb.dtsi for motherboard, axc001.dtsi and axc003.dtsi for cpu tiles and axs101.dts and axs103.dts to represent actual boards. Also we delete axs10x.dts as it is no longer used. One more important change - we add timer device to ARC skeleton device tree sources as both ARC700 and ARCHS cores contain such timer. We add core_clk nodes to abilis_tb100, nsim, axc001 and axc003 device tree sources as it is referenced via phandle from timer node in common skeleton.dtsi file.

Commit e2f88dfd2d96 ("libfdt: Introduce new ARCH_FIXUP_FDT option") allows us to skip memory setup of DTB, but a problem for ARM is that spin_table_update_dt() and psci_update_dt() are skipped as well if CONFIG_ARCH_FIXUP_FDT is disabled. This commit allows us to skip only fdt_fixup_memory_banks() instead of the whole of arch_fixup_fdt().

2016-08-05arc: Rename AXS101 board to more generic AXS10xAlexey Brodkin
As of now we have 2 flavors of ARC SDP boards: 1) AXS101 - with ARC770 in ASIC 2) AXS103 - with ARC HS38 in FPGA Both options share exactly the same base-board and only differ with CPU-tiles in use. That means all peripherals are the same (they are implemented in FPGA on the base-board) and so generic board could be used for both.

2016-06-13arc: Update data accessors with use of memory barriersAlexey Brodkin
Memory barriers are proven to be a requirement for both compiler and real hardware to properly serialize access to critical data. For example if CPU or data bus it uses may do reordering of data accesses absence of memory barriers might easily lead to very subtle and hard to debug data corruptions. This implementation was heavily borrowed from up to date Linux kernel. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2016-06-13arc/cache: Flush & invalidate all caches right before enabling IOCAlexey Brodkin
According to ARC HS databook it is required to flush and disable caches prior programming IOC registers. Otherwise ongoing coherent memory operations may not observe the coherency protocols as expected. But since in ARC HS v2.1 there's no way to disable SLC (AKA L2 cache) we're doing our best flushing and invalidating it. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2016-06-13arc/cache: really do invalidate_dcache_all() even if IOC existsAlexey Brodkin
invalidate_dcache_all() could be used in different use-cases and what is especially important most of those cases won't be related to DMAed data to or from peripherals, i.e. we'll be doing invalidation of data used purely by CPU cores. Given that IOC engine only snoops data that goes through DMA we need to care ourselves about data used only by CPU cores and so remove dependency on IOC from invalidate_dcache_all() and always do real invalidation.

2016-04-21arc/cache: really do flush_dcache_all() even if IOC existsAlexey Brodkin
flush_dcache_all() is used in the very end of U-Boot self relocation to write back all copied and then patched code and data to their new location in the very end of available memory space. Since that has nothing to do with IO (i.e. no external DMA happens here) IOC won't help here and we need to write back data cache contents manually.

2016-02-20arc: cache - utilize IO coherency (AKA IOC) engineAlexey Brodkin
With release of ARC HS38 v2.1 new IO coherency engine could be built-in ARC core. This hardware module ensures coherency between DMA-ed data from peripherals and L2 cache. With L2 and IOC enabled there's no overhead for L2 cache manual maintenance which results in significantly improved IO bandwidth. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2016-02-20arc: cache - accommodate different L1 cache line lengthsAlexey Brodkin
ARC core could be configured with different L1 and L2 (AKA SLC) cache line lengths. At least these values are possible and were really used: 32, 64 or 128 bytes. Current implementation requires cache line to be selected upon U-Boot configuration and then it will only work on matching hardware. Indeed this is quite efficient because cache line length gets hardcoded during code compilation. But OTOH it makes binary less portable. With this commit we allow U-Boot to determine real L1 cache line length early in runtime and use this value later on. This extends portability of U-Boot binary a lot.

2015-07-01arc: significant cache reworkAlexey Brodkin
[1] Align cache management functions to those in Linux kernel. I.e.: a) Use the same functions for all cache ops (D$ Inv/Flush) b) Split cache ops in 3 sub-functions: "before", "lineloop" and "after". That way we may re-use "before" and "after" functions for region and full cache ops. [2] Implement full-functional L2 (SLC) management. Before SLC was simply disabled early on boot. It's also possible to enable or disable L2 cache from config utility. [3] Disable/enable corresponding caches early on boot. So if U-Boot is configured to use caches they will be used at all times (this is useful in partucular for speed-up of relocation). Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-07-01arc: implement slave cores kick-start for Linux kernelAlexey Brodkin
With new SMP-enabled CPUs with ARC HS38 cores and corresponding support in Linux kernel it's required to add basic SMP support in U-Boot. Currently we assume the one and only core starts execution after power-on. So most of things in U-Boot is handled in UP mode. But when U-Boot is used for loading and starting Linux kernel right before jumping to kernel's entry point U-Boot: [1] Sets all slave cores to jump to the same address [kernel's entry point] [2] Really starts all slav cores In ARC's implemetation of SMP in Linux kernel all cores are supposed to run the same start-up code. But only core with ID 0 (master core) processes further while others are looping waiting for master core to complete some initialization. That means it's safe to un-pause slave cores and let them execute kernel - they will wait for master anyway.

This is important to have entry point in the beginning of .text section because it allows simple loading and execution of U-Boot. For example pre-bootloader loads U-Boot in memory starting from offset 0x81000000 and then just jumps to the same address. Otherwise pre-bootloader would need to find-out where entry-point is.
