[U-Boot] [PATCH V2 1/4] tegra: remove some cruft from CONFIG_EXTRA_ENV_SETTINGS
by Stephen Warren 01 Jun '12

01 Jun '12

From: Stephen Warren <swarren(a)nvidia.com> console isn't used by anything, and the kernel should be set appropriately by whatever script is booting the kernel, not imposed by the bootloader. mem might be useful, but the current value is pretty bogus, since it includes nvmem options that make no sense for an upstream kernel, and equally should not be required for any downstream kernel. Either way, this is also best left to the kernel boot script. smpflag isn't used by anything, and again was probably intended to be a kernel command-line option better set by the kernel boot script.

[U-Boot] [PATCH V2 1/2] spi: Tegra2: Seaboard: fix UART corruption during SPI transactions
by Tom Warren 01 Jun '12

01 Jun '12

Simon Glass's proposal to fix this on Seaboard was NAK'd, so I removed his NS16550 references and added a small delay before SPI/UART muxing. Tested on my Seaboard with large SPI reads/writes and saw no corruption (crc's matched) and no spurious comm chars.

[U-Boot] [PATCH V2] tegra: Whistler board support
by Stephen Warren 01 Jun '12

01 Jun '12

From: Stephen Warren <swarren(a)nvidia.com> Whistler is a highly configurable Tegra evaluation and development board. This change adds support for the following specific configuration: E1120 motherboard E1108 CPU board E1116 PMU board The motherboard configuration switches are set as follows: SW1=0 SW2=0 SW3=5 S1/S2/S3/S4 all on, except S3 7/8 are off. Other combinations of daugher boards may work to varying degrees, but will likely require some SW adjustment. Signed-off-by: Stephen Warren <swarren(a)nvidia.com> --- v2: Include <i2c.h> to fix implicit declaration warnings. This still depends on "tegra: add alternate UART1 funcmux entry", but since that didn't change, I didn't repost that.

Please see the 'Patches' entry on the U-Boot wiki, specifically 'Sending updated patch versions'. > Yes, I intend to drop the first patch, as my need to support multiple RAM configurations with a single u-boot image is addressed by your patch to load the ODMDATA from the BCT. Though I still dislike this duplication of information between MC config and ODMDATA, but I think it's a waste of time to argue about this, as it is way above my head. Sorry for not properly versioning those two patches, I'll do so in the future. Thanks, Lucas

[U-Boot] [PATCH v2 0/4] kirkwood spi_claim/release_bus support
by Valentin Longchamp 31 May '12

31 May '12

This series adds generic support for the spi_claim/release_bus functions for the kirkwood processors. The implementation was already discussed in another thread following my first board specific submission of the patch. The series adds two functions to the kirkwood mpp code to be able to temporarily save and then restore the mpp configuration. Changes for v2: - save MPP configuration with mpp_read function as dicussed on ML - moved CS pin MPP config to spi_setup_slave only - add backup fo CS pin in spi_setup_slave and reset in spi_free_slave Valentin Longchamp (4): kirkwood: add kirkwood_mpp_read function kw_spi: backup and reset the MPP of the chosen CS pin kw_spi: support spi_claim/release_bus functions kw_spi: add weak functions board_spi_claim/release_bus arch/arm/cpu/arm926ejs/kirkwood/mpp.c | 41 +++++++++++++++++++ arch/arm/include/asm/arch-kirkwood/mpp.h | 1 + arch/arm/include/asm/arch-kirkwood/spi.h | 11 +++++ drivers/spi/kirkwood_spi.c | 65 +++++++++++++++++++++++++---- 4 files changed, 109 insertions(+), 9 deletions(-)
