[U-Boot] [PATCH] DaVinci DM6467: Added ET1011C (LSI) PHY support
by s-paulraj＠ti.com 28 Dec '10

28 Dec '10

From: Sandeep Paulraj <s-paulraj(a)ti.com> Added a driver for handling ET1011C gigabit phy. which overrides get_link_speed function from default implementation. This enables output of 125 MHz reference clock on SYS_CLK pin.

[U-Boot] Updating a system
by David Lynch Jr. 28 Dec '10

28 Dec '10

I need to setup a system so that it can boot a user web updateable kernel/rootfs or a failsafe version. The process has to be manageable by completely non-technical users and work from a single flash media - no plugging in an SD card or USB stick to recover. Before I re-invent the wheel is there an existing scheme to manage multiple boot choices with an automatic fallback to a failsafe ? -- Dave Lynch DLA Systems Software Development: Embedded Linux 717.587.7774 dhlii(a)dlasys.net http://www.dlasys.net Over 25 years' experience in platforms, languages, and technologies too numerous to list.

[U-Boot] [PATCH] fsl_esdhc: Fix esdhc disabled problem on some platforms
by Chenhui Zhao 28 Dec '10

28 Dec '10

Some platform's esdhc pins don't share with other function. The eSDHC shouldn't be disabled, even if "esdhc" isn't defined in hwconfig env variable. Use CONFIG_FSL_ESDHC_PIN_MUX to fix this problem. The problem was introduced by this commit: commit b33433a63fe08c9e723ea15a7c7c7143bf527c6d Author: Anton Vorontsov <avorontsov(a)ru.mvista.com> Date: Wed Jun 10 00:25:29 2009 +0400 fsl_esdhc: Add device tree fixups Signed-off-by: Chenhui Zhao <b26998(a)freescale.com> Signed-off-by: Li Yang <leoli(a)freescale.com> --- drivers/mmc/fsl_esdhc.c | 2 ++ include/configs/MPC837XEMDS.h | 1 + include/configs/MPC837XERDB.h | 1 + include/configs/MPC8569MDS.h | 1 + 4 files changed, 5 insertions(+), 0 deletions(-) diff --git a/drivers/mmc/fsl_esdhc.c b/drivers/mmc/fsl_esdhc.c index cd78714..4c8caa9 100644 --- a/drivers/mmc/fsl_esdhc.c +++ b/drivers/mmc/fsl_esdhc.c @@ -527,10 +527,12 @@ void fdt_fixup_esdhc(void *blob, bd_t *bd) const char *compat = "fsl,esdhc"; const char *status = "okay"; +#ifdef CONFIG_FSL_ESDHC_PIN_MUX if (!hwconfig("esdhc")) { status = "disabled"; goto out; } +#endif do_fixup_by_compat_u32(blob, compat, "clock-frequency", gd->sdhc_clk, 1); diff --git a/include/configs/MPC837XEMDS.h b/include/configs/MPC837XEMDS.h index c237991..abccfd6 100644 --- a/include/configs/MPC837XEMDS.h +++ b/include/configs/MPC837XEMDS.h @@ -509,6 +509,7 @@ extern int board_pci_host_broken(void); #ifdef CONFIG_MMC #define CONFIG_FSL_ESDHC +#define CONFIG_FSL_ESDHC_PIN_MUX #define CONFIG_SYS_FSL_ESDHC_ADDR CONFIG_SYS_MPC83xx_ESDHC_ADDR #define CONFIG_CMD_MMC #define CONFIG_GENERIC_MMC diff --git a/include/configs/MPC837XERDB.h b/include/configs/MPC837XERDB.h index 385c7c3..ea3056b 100644 --- a/include/configs/MPC837XERDB.h +++ b/include/configs/MPC837XERDB.h @@ -517,6 +517,7 @@ #ifdef CONFIG_MMC #define CONFIG_FSL_ESDHC +#define CONFIG_FSL_ESDHC_PIN_MUX #define CONFIG_SYS_FSL_ESDHC_ADDR CONFIG_SYS_MPC83xx_ESDHC_ADDR #define CONFIG_CMD_MMC #define CONFIG_GENERIC_MMC diff --git a/include/configs/MPC8569MDS.h b/include/configs/MPC8569MDS.h index 9620fd0..f4a3c2f 100644 --- a/include/configs/MPC8569MDS.h +++ b/include/configs/MPC8569MDS.h @@ -561,6 +561,7 @@ extern unsigned long get_clock_freq(void); #ifdef CONFIG_MMC #define CONFIG_FSL_ESDHC +#define CONFIG_FSL_ESDHC_PIN_MUX #define CONFIG_SYS_FSL_ESDHC_ADDR CONFIG_SYS_MPC85xx_ESDHC_ADDR #define CONFIG_CMD_MMC #define CONFIG_GENERIC_MMC -- 1.6.4.1
