[PATCH] mtd: add prototypes for weak function
by Patrick Delaunay 25 Jan '20

25 Jan '20

This patch adds a prototype for the weak function board_mtdparts_default().

[PATCH] lib: rsa: consider CONFIG_SPL_RSA
by Heinrich Schuchardt 25 Jan '20

25 Jan '20

CONFIG_SPL_RSA is meant to control if lib/rsa/* is used for SPL. Adjust lib/Makefile to consider this setting. This was correctly setup with commit 51c14cd128f4 ("verified-boot: Minimal support for booting U-Boot proper from SPL") and got lost with commit 089df18bfe9d ("lib: move hash CONFIG options to Kconfig").

[PATCH v2 0/4] dma-mapping: Add cache flush/invalidation to dma_{un}map_single
by Vignesh Raghavendra 25 Jan '20

25 Jan '20

Drivers (especially frameworks ported from Linux such as USB) expect dma_{un}map_single() APIs to take care of cache maintenance. But this is not the case in U-Boot and few drivers take care of flushing caches locally. Instead add flush/invalidate calls to DMA APIs in arch specific dma-mapping.h file so that per driver implementation of these APIs can be avoided. travis-ci is green: https://travis-ci.org/r-vignesh/u-boot/builds/637784160 v2: Fix compilation failure on AM335x etc due to recent U-Boot changes Collect R-bys Vignesh Raghavendra (4): asm: dma-mapping.h: Fix dma mapping functions mmc: tmio-common: Drop custom dma mapping functions mtd: denali: Drop custom dma mapping functions net: macb: Drop local cache flush arch/arm/include/asm/dma-mapping.h | 23 ++++++++++++++++-- arch/nds32/include/asm/dma-mapping.h | 23 ++++++++++++++++-- arch/riscv/include/asm/dma-mapping.h | 23 ++++++++++++++++-- arch/x86/include/asm/dma-mapping.h | 23 ++++++++++++++++-- drivers/mmc/tmio-common.c | 25 +++----------------- drivers/mtd/nand/raw/denali.c | 35 +++------------------------- drivers/net/macb.c | 4 +--- 7 files changed, 91 insertions(+), 65 deletions(-) -- 2.25.0
