Kconfig: Add SPI / SPI_FLASH as dependencies

2019-06-13T07:21:06Z

In order to use CMD_SF / CMD_SPI / ENV_IS_IN_SPI_FLASH we need to have the SPI (or SPI_FLASH/DM_SPI_FLASH, for CMD_SF) enabled. Express this in the Kconfigs. Signed-off-by: Tom Rini Reviewed-by: Jagan Teki

m68k: add OF control support to m68k

2019-05-09T16:36:17Z

Improvements and new features: - split more rockchip pinctrl_core feature into per SoC - enable TPL for evb-rk3399 board - enable TPL/SPL for evb-px5 board - enable TPL and OP-TEE support for evb-rk3229 - update fix in arm common assembly start code for rockchip header file - update default SPL_FIT_GENERATOR for rockchip - rk3399 boards update to use '-u-boot.dtsi' - add new rk3399 boards: Nanopi M4, Nanopc T4 - enable sound for chromebook_minnie

sysreset: enable driver support in SPL/TPL

SPL/TPL also need use sysreset for some feature like panic callback. Signed-off-by: Kever Yang

x86: Enable the RTC on all boards

2019-05-08T05:02:18Z

With the move to Kconfig this option should be set in Kconfig, not in the config header file. Move it. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Support SPL and TPL

2019-05-08T05:02:11Z

At present only chromebook_link64 supports SPL. It is useful to eb able to support both TPL and SPL to implement verified boot on x86. Enable the options for both along with some suitable default options needed to boot through these phases. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

arch: armv8: Provide a way to disable cache maintenance ops

2019-05-05T12:48:50Z

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.

x86: sandbox: pch: Add a CONFIG option for PCH

2019-02-20T07:25:30Z

At present this uclass is selected only on x86. In order to add a test for it, it must also support sandbox. Create a new CONFIG_PCH option and enable it on x86 and sandbox. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

dm: sound: Create an option to use driver model for sound

2018-12-13T23:32:49Z

The U-Boot sound system provides basic support for beeping. At present it does not use driver model, but it needs to be converted. Add an option to enable driver model for sound. For now it is not connected to anything. Future work will add drivers which use this option. It will then be removed once everything is converted. Signed-off-by: Simon Glass
