[U-Boot] [RFC] [PATCH] DaVinci/i2c: allow multiple buses

Hi Tom, I'm requesting comments on the following (untested) patch. It adds support for multiple i2c buses on davinci_i2c, without altering one line of code. What I don't like is that I'm doing a bit of macro black magic to transform constants into variables. But I don't know whether refactoring

[U-Boot] [PATCH] spi_flash/stmicro: add geometrical info for N25Q256 from Micron

Note: because 4-byte addressing is not supported yet, at the moment only the first 16MiB of the device are available. Signed-off-by: Jérôme Carretero CC: Mike Frysinger --- drivers/mtd/spi/stmicro.c |7 +++ 1 file changed, 7 insertions(+) diff --git a/drivers/mtd/spi/stmicro.c b

[U-Boot] [PATCH] davinci/spi: allow usage of other chip selects and buses

Use the spi_slave bus and cs attributes, reduce C2T/T2C delays, allow overriding of spi_cs_is_valid(). As it is, this patch breaks the configuration files for DaVinci boards that only use SPI1. Signed-off-by: Jérôme Carretero CC: Manjunathappa, Prakash -- drivers/spi/davinci_spi.c | 16

[PATCH] spl: allow boot from first bootable partition

This was implemented in order to get dual-slot bootloader partitions on the BeagleBone Black, whose MLO boots from the first bootable partition: MLO chainloads u-boot in the same way. Signed-off-by: Jérôme Carretero --- common/spl/Kconfig | 3 ++- common/spl/spl_mmc.c | 33

[PATCH v2] boot: image: fixup zstd decompression buffer initialization typo

The code was mistakenly initializing the input buffer twice. Tested to be working on BeagleBone by adjusting CONFIG_SYS_BOOTM_LEN to 64MiB (probably works with less) and preparing uImage with: cat arch/arm/boot/Image \ | zstd --ultra -22 --zstd=windowLog=22 \ > linux.bin.zst mkimage -A arm
