[U-Boot] [PATCH v2 5/8] sf: winbond: Update the names for W25Q 0x40XX ID's flash parts
by Jagannadha Sutradharudu Teki 05 Jun '13

05 Jun '13

Use the exact names for W25Q 0x40XX ID's flash parts, as the same sizes of flashes comes with different ID's. so-that the distinguishes becomes easy with this change.

[U-Boot] [PATCH v2] mmc: Update "mmc->part_num" when performing a partition switch
by Fabio Estevam 05 Jun '13

05 Jun '13

When running the "save" command several times on a mx6qsabresd we see: U-Boot > save Saving Environment to MMC... Writing to MMC(1)... done U-Boot > save Saving Environment to MMC... MMC partition switch failed U-Boot > save Saving Environment to MMC... Writing to MMC(1)... done U-Boot > save Saving Environment to MMC... MMC partition switch failed U-Boot > save Saving Environment to MMC... Writing to MMC(1)... done U-Boot > save Saving Environment to MMC... MMC partition switch failed Fix this by updating mmc->part_num inside mmc_switch_part() after a succesful mmc partition switch. After this fix, we no longer see the error after the "save" command on a mx6qsabresd. Also tested on a mx53loco.

[U-Boot] [PATCH] arm: Remove OMAP2420H4 and all omap24xx support
by Tom Rini 05 Jun '13

05 Jun '13

The omap2420H4 was the only mainline omap24xx board. Prior to being fixed by Jon Hunter in time for v2013.04 it had been functionally broken for a very long time. Remove this board as there's not been interest in it in U-Boot for quite a long time.

[U-Boot] [PATCH V5] ARM: OMAP: I2C: New read, write and probe functions
by Lubomir Popov 04 Jun '13

04 Jun '13

New i2c_read, i2c_write and i2c_probe functions, tested on OMAP4 (4430/60/70), OMAP5 (5430) and AM335X (3359); should work on older OMAPs and derivatives as well. The only anticipated exception would be the OMAP2420, which shall require driver modification. - Rewritten i2c_read to operate correctly with all types of chips (old function could not read consistent data from some I2C slaves). - Optimised i2c_write. - New i2c_probe, performs write access vs read. The old probe could hang the system under certain conditions (e.g. unconfigured pads). - The read/write/probe functions try to identify unconfigured bus. - Status functions now read irqstatus_raw as per TRM guidelines (except for OMAP243X and OMAP34XX). - Driver now supports up to I2C5 (OMAP5). Signed-off-by: Lubomir Popov <lpopov(a)mm-sol.com> --- V5 changes: - Replaced some printf() with puts(). - Minor formatting touches, checkpatch-clean. V4 changes: - New i2c_probe is built unconditionally, old code is removed. CONFIG_I2C_PROBE_WRITE is no longer needed. - Added a small delay to work around breakage in AM335X SPL. - Some whitespace and general formatting cleanup. V3 changes: - Removed old functions and conditional compilation. New functions are now built unconditionally for all SoCs using this driver. The only chip that should break is the OMAP2420 dinosaur. - Interrupts are enabled for OMAP243X and OMAP34XX only (where we don't have an irqstatus_raw register). V2 changes: - Probe tries to identify misconfigured pads as well. - Status is retrieved from irqstatus_raw rather than from stat. - Some minor style & format changes. drivers/i2c/omap24xx_i2c.c | 490 +++++++++++++++++++++++++++------------------ 1 file changed, 299 insertions(+), 191 deletions(-) diff --git a/drivers/i2c/omap24xx_i2c.c b/drivers/i2c/omap24xx_i2c.c index 54e9b15..ef38d71 100644 --- a/drivers/i2c/omap24xx_i2c.c +++ b/drivers/i2c/omap24xx_i2c.c @@ -18,6 +18,20 @@ * * Adapted for OMAP2420 I2C, r-woodruff2(a)ti.com * + * Copyright (c) 2013 Lubomir Popov <lpopov(a)mm-sol.com>, MM Solutions + * New i2c_read, i2c_write and i2c_probe functions, tested on OMAP4 + * (4430/60/70), OMAP5 (5430) and AM335X (3359); should work on older + * OMAPs and derivatives as well.

[U-Boot] [PATCH] ARM: tegra: only enable SCU on Tegra20
by Stephen Warren 04 Jun '13

04 Jun '13

From: Tom Warren <twarren(a)nvidia.com> The non-SPL build of U-Boot on Tegra only runs on a single CPU, and hence there is no need to enable the SCU when running U-Boot. If an SMP OS is booted, and it needs the SCU enabled, it will enable the SCU itself. U-Boot doing so is redundant. The one exception is Tegra20, where an enabled SCU is required for some aspects of PCIe to work correctly. Some Tegra SoCs contain CPUs without a software-controlled SCU. In this case, attempting to turn it on actively causes problems. This is the case for Tegra114. For example, when running Linux, the first (or at least some very early) user-space process will trigger the following kernel message: Unhandled fault: imprecise external abort (0x406) at 0x00000000 This is typically accompanied by that process receving a fatal signal, and exiting. Since this process is usually pid 1, this causes total system boot failure.

[U-Boot] [PATCH] common: env_mmc: Make mmc->part_num in sync after a partition switch
by Fabio Estevam 04 Jun '13

04 Jun '13

When running the "save" command several times on a mx6qsabresd we see: U-Boot > save Saving Environment to MMC... Writing to MMC(1)... done U-Boot > save Saving Environment to MMC... MMC partition switch failed U-Boot > save Saving Environment to MMC... Writing to MMC(1)... done U-Boot > save Saving Environment to MMC... MMC partition switch failed U-Boot > save Saving Environment to MMC... Writing to MMC(1)... done U-Boot > save Saving Environment to MMC... MMC partition switch failed Fix this by making mmc->part_num to be in sync with CONFIG_SYS_MMC_ENV_PART after the partition has been changed in mmc_switch_part(). After this fix, we no longer see the error after the "save" command on a mx6qsabresd. Also tested on a mx53loco.
