2019-07-18arm: move CONFIG_TFABOOT to generic KconfigAKASHI Takahiro
Currently, CONFIG_TFABOOT is located in armv8/fsl-layerscape Kconfig, but it will be also useful for other targets if some additional configuration are necessary. So move it to arch/arm/Kconfig. Please note that CONFIG_TFABOOT still depends on CONFIG_ARCH_SUPPORT_TFABOOT and so the menu won't come up if any target doesn't need its own customization for TF-A boot. This will maintain the compatibility.

2019-07-10arm64: add an option to switch visibility of CONFIG_SYS_INIT_SP_BSS_OFFSETMasahiro Yamada
By default, CONFIG_SYS_INIT_SP_BSS_OFFSET was made invisible by not giving a prompt to it. The only way to define it is to hard-code an extra entry in SoC/board Kconfig, like arch/arm/mach-tegra/tegra{186,210}/Kconfig. Add a prompt to it in order to allow defconfig files to specify the value of CONFIG_SYS_INIT_SP_BSS_OFFSET. With this, CONFIG_SYS_INIT_SP_BSS_OFFSET would become always visible. So, we need a new bool option to turn it off by default. I move the 'default 524288' to the common place. This value is not too big, but is big enough to avoid the overwrap of DT in most platforms. If 512KB is not a suitable choice for your platform, you can change it from your defconfig or menuconfig etc. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Stephen Warren <swarren@nvidia.com>

2019-06-19armv8/fsl-layerscape: Add loop to check L3 dcache statusMeenakshi Aggarwal
Flushing L3 cache may need variable time depending upon cache line allocation. Coming up with a proper timeout value would be best handled by simulations under multiple scenarios in your actual system. >From the purely HN-F point of view, the flush would take ~15 cycles for a clean line, and ~22 cycles for a dirty line. For the dirty line case, there are many variables outside the HN-F that will increase the duration per line. For example, a *DBIDResp from the SN-F/SBSX, memory controller latency, SN-F/SBSX RetryAck responses, CCN ring congestion, CCN ring hops, etc, etc. The worst-case timeout would have to factor in all of these variables plus the HN-F cycles for every line in the L3, and assuming all lines are dirty In case if L3 is not flushed properly, system behaviour will be erratic, so remove timeout and add loop to check status of L3 cache. System will stuck in while loop if there is some issue in L3 cache flushing.

2019-05-05arch: armv8: Provide a way to disable cache maintenance opsVignesh Raghavendra
On AM654 SoC(arm64) which is IO coherent and has L3 Cache, cache maintenance operations being done to support non-coherent platforms causes issues. For example, here is how U-Boot prepares/handles a buffer to receive data from a device (DMA Write). This may vary slightly depending on the driver framework: Start DMA to write to destination buffer Wait for DMA to be done (dma_receive()/dma_memcpy()) Invalidate destination buffer (invalidate_dcache_range()) Read from destination buffer The invalidate after the DMA is needed in order to read latest data from memory that’s updated by DMA write. Also, in case random prefetch has pulled in buffer data during the “wait for DMA” before the DMA has written to it. This works well for non-coherent architectures. In case of coherent architecture with L3 cache, DMA write would directly update L3 cache contents (assuming cacheline is present in L3) without updating the DDR memory. So invalidate after “wait for DMA” in above sequence would discard latest data and read will cause stale data to be fetched from DDR. Therefore invalidate after “wait for DMA” is not always correct on coherent architecture. Therefore, provide a Kconfig option to disable cache maintenance ops on coherent architectures. This has added benefit of improving the performance of DMA transfers as we no longer need to invalidate/flush individual cache lines(especially for buffer thats several KBs in size). In order to facilitate use of same Kconfig across different architecture, I have added the symbol to top level arch/Kconfig file. Patch currently disables cache maintenance ops for arm64 only. flush_dcache_all() and invalidate_dcache_all() are exclusively used during enabling/disabling dcache and hence are not disabled.
