[U-Boot] [PATCH v6] mx6: Read silicon revision from register
by Fabio Estevam 22 Mar '12

22 Mar '12

Instead of hardcoding the mx6 silicon revision, read it in run-time. Also, besides the silicon version print the mx6 variant type: quad,dual/solo or solo-lite. Tested on a mx6qsabrelite, where it shows: CPU: Freescale i.MX6Q rev1.0 at 792 MHz Signed-off-by: Fabio Estevam <fabio.estevam(a)freescale.com> --- Changes since v5: - Avoid duplication of code. Also tested on a mx51evk board. Changes since v4: - Distinguish the the CPU print depending on the SoC type (MX5 or MX6) Changes since v3: - Provide a complete struct for anatop registers Changes since v2: - Read both chip variant and chip silicon version from anatop - Create a struct for accessing the anatop registers Changes since v1: - Fix typo on Subject arch/arm/cpu/armv7/imx-common/cpu.c | 24 +++++- arch/arm/cpu/armv7/mx6/soc.c | 8 ++- arch/arm/include/asm/arch-mx6/imx-regs.h | 142 ++++++++++++++++++++++++++++++ 3 files changed, 171 insertions(+), 3 deletions(-) diff --git a/arch/arm/cpu/armv7/imx-common/cpu.c b/arch/arm/cpu/armv7/imx-common/cpu.c index 6d7486b..3d58d8a 100644 --- a/arch/arm/cpu/armv7/imx-common/cpu.c +++ b/arch/arm/cpu/armv7/imx-common/cpu.c @@ -64,13 +64,33 @@ static char *get_reset_cause(void) } #if defined(CONFIG_DISPLAY_CPUINFO) + +static char *get_imx_type(u32 imxtype) +{ + switch (imxtype) { + case 0x63: + return "6Q";

[U-Boot] [PATCH 1/5] Revert "Add board_pre_console_putc to deal with early console output"
by Simon Glass 22 Mar '12

22 Mar '12

This reverts commit 295d3942b806552503243f5cfb36aec6f1b5a9bf. It turns that this really doesn't work very nicely. Instead we should have a pre-console panic function so that we know that further execution is impossible and we don't need to worry about trampling on UARTs, etc. Signed-off-by: Simon Glass <sjg(a)chromium.org> --- README | 17 ----------------- common/console.c | 10 +--------- include/common.h | 7 ------- 3 files changed, 1 insertions(+), 33 deletions(-) diff --git a/README b/README index 7adf7c7..84757a5 100644 --- a/README +++ b/README @@ -638,23 +638,6 @@ The following options need to be configured: 'Sane' compilers will generate smaller code if CONFIG_PRE_CON_BUF_SZ is a power of 2 -- Pre-console putc(): - Prior to the console being initialised, console output is - normally silently discarded.

If you make u-boot.img it doesn't also make in the SPL directory. Can this get fixed before the next release? -- Jon Smirl jonsmirl(a)gmail.com

[U-Boot] [PATCH] mmc: omap: handle controller errors properly
by Grazvydas Ignotas 21 Mar '12

21 Mar '12

According to OMAP3 TRM, when the controller reports certain errors, driver must perform a software reset. This is done by setting a bit in SYSCTL and waiting it to clear: - SRC on command timeout (CTO) - SRD on data errors (DTO, DCRC and DEB) This fixes a problem seen on OMAP3 pandora board with some cards that won't work with a message printed multiple times: timedout waiting on cmd inhibit to clear Code loosely based on Linux omap_hsmmc driver.
