[U-Boot] [PATCH 1/1] efi_loader: sanity checks when freeing memory
by Heinrich Schuchardt 31 Mar '19

Use a checksum to validate that efi_free_pool() is only called for memory allocated by efi_allocated_pool(). Add a plausibility check to efi_free_pages() checking that the address passed is page aligned. Update related function comments to match Sphinx style.

[U-Boot] [PATCH] dm: remove pre reloc properties in SPL and TPL device tree
by Patrick Delaunay 30 Mar '19

30 Mar '19

We can remove the pre reloc property in SPL and TPL device-tree: - u-boot,dm-pre-reloc - u-boot,dm-spl - u-boot,dm-tpl As only the needed node are kept by fdtgrep (1st pass). The associated function (XXX_pre_reloc) are simple for SPL/TPL: return always true. Signed-off-by: Patrick Delaunay <patrick.delaunay(a)st.com> --- remove pre reloc properties in SPL and TPL device tree Patch created after some remarks on previous http://patchwork.ozlabs.org/patch/1035797/ I check the current code and I found a way to reduce the SPL device tree size: remove the un-necessary pre reloc parameters in SPL/TPL DT (as the node check is already managed by fdtgrep) But I need to change the DM code to avoid the check on presence of this parameters... On my board stm32mp1-ev1, the SPL device tree is reduced by 790 bytes (11149 to 10419) and the SPL binary u-boot-spl.stm32 by 798 bytes (64745 to 63947); the boot is not broken and I have the expected delta between generated device tree. But I don't sure that I see all the side impact of the code change in SPL/TPL. PS: I already see a side effect on this patch, because all node are now bounded in SPL/TPL, it is no more needed to TAG all the device tree path but only the last needed children.

[U-Boot] [PATCH] mmc: dw_mmc: Handle return value from bounce_buffer_start()
by Marek Vasut 30 Mar '19

30 Mar '19

The bounce_buffer_start() can return -ENOMEM in case memory allocation failed. However, in that case, the bounce buffer address is the same as the possibly unaligned input address, and the cache maintenance operations were not applied to this address. This could cause subtle problems. Add handling for the bounce_buffer_start() return value to prevent such a problem from happening.

[U-Boot] [RFC PATCH v1 0/9] Add support for applications of overlays in SPL
by Jean-Jacques Hiblot 30 Mar '19

30 Mar '19

The purpose of this series is to provide the SPL with ability to apply overlays for u-boot. this is only a RFC so far, to get a feedback on the approach. Our use-case is the support of the daughter boards of the AM65x EVM. In Linux, each board is supported by a unique overlay. The presence of the boards is detected at runtime, and some useful features (like USB) are implemented on those daughter boards. Instead of providing multiple dtbs and fall in a combinatorial pit, we propose to use DT overlays. The first 4 patches are small fixes/improvement related to the build. Patch #5 may be a bit controversial. It basically replaces u-boot.img with a symlink to u-boot.itb in case we use a "complex" FIT (ie: if SPL_FIT_SOURCE or SPL_FIT_GENERATOR are set) Patch #6 and #7 are the core support for DTB application in the SPL. Based on a patch posted by Michal Simek a few weeks ago. The list of overlays is read from the "fdt" of the configuration chosen in the ITB (same property as for the DTB): configurations { default = "conf-1"; conf-1 { description = "dra76-evm"; firmware = "firmware-1"; fdt = "fdt-1", "overlay-1"; }; } Patch #8 adds a way to dynamically select the DT overlays. That is were we would use HW detection to select the required overlays. In that case, the board-level code tells what overlay it needs (it gives the name of the node). Patch #9 is not required, but demonstrates on a DRA76-evm how this series can be used. Jean-Jacques Hiblot (8): dtbo: also generate dtbo from dtso Makefile.lib: include /__symbols__ in dtb if OF_LIBFDT_OVERLAY is enabled Makefile: Fix u-boot.itb generation when building outside the source tree Makefile: Pass the board name to the FIT generator scripts Makefile: use custom ITS to build u-boot.img if SPL_FIT_SOURCE or SPL_FIT_GENERATOR are set spl: fit: Allow calling spl_load_fit_image() to only get the image size sp: fit: Allow the board to dynamically select the DTB overlays it needs. !!!

[U-Boot] [PATCHv3 0/6] dm: cache: add dm cache driver
by Dinh Nguyen 30 Mar '19

30 Mar '19

Hi, This is V3 of the series to add a UCLASS_CACHE dm driver to handling the configuration of cache settings. Place this new driver under /drivers/cache. In this initial revision, the driver is only configuring what I think are essential cache settings. The more comprehensive cache settings can be done in the OS. Diffs from v2: - Add cache_get_info() to check for non-zero value - Add comments to cache_info struct - Fix up nits from Simon Glass Dinh Nguyen (6): Documentation: dts: Add pl310 cache controller dts documentation ARM: pl310: Add macro's for handling tag and data latency mask dm: cache: Create a uclass for cache dm: cache: add the pl310 cache controller driver ARM: socfpga: use the pl310 driver to configure the cache configs: socfpga: add imply pl310 cache controller .../devicetree/bindings/arm/l2c2x0.txt | 114 ++++++++++++++++++ arch/arm/Kconfig | 1 + arch/arm/include/asm/pl310.h | 3 + arch/arm/mach-socfpga/misc.c | 16 +-- drivers/Kconfig | 2 + drivers/Makefile | 1 + drivers/cache/Kconfig | 25 ++++ drivers/cache/Makefile | 4 + drivers/cache/cache-l2x0.c | 76 ++++++++++++ drivers/cache/cache-uclass.c | 24 ++++ drivers/cache/sandbox_cache.c | 34 ++++++ include/cache.h | 38 ++++++ include/dm/uclass-id.h | 1 + test/dm/cache.c | 20 +++ 14 files changed, 346 insertions(+), 13 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/l2c2x0.txt create mode 100644 drivers/cache/Kconfig create mode 100644 drivers/cache/Makefile create mode 100644 drivers/cache/cache-l2x0.c create mode 100644 drivers/cache/cache-uclass.c create mode 100644 drivers/cache/sandbox_cache.c create mode 100644 include/cache.h create mode 100644 test/dm/cache.c -- 2.20.0
