[U-Boot] Reading multiple bytes using I2C in U-Boot
by Nildo Junior 26 Jul '14

26 Jul '14

I am having a problem with the I2C driver for a Freescale p1022tw board. There is the command on U-Boot's console to read from an I2C device: i2c md chip address[.0, .1, .2] [# of objects] When I read 4 bytes from a device with id 0x60, at address 0x0, I get: tw=>i2c md 60 0 4 0000: 45 45 45 45 EEEE These values that it returned are wrong. I can get the right values if I read one byte at the time: tw=>i2c md 60 0 1 0000: 45 E tw=>i2c md 60 1 1 0001: 45 E tw=>i2c md 60 2 1 0002: 46 F tw=>i2c md 60 3 1 0003: 00 . I should have gotten `45 45 46 00` or `EEF0` in the first command. In multiple readings for this device, it is returning always just the first byte value. If I try to get 6 bytes starting at address 0x2, this is the output: tw=>i2c md 60 2 6 0002: 46 46 46 46 46 46 FFFFFF This problem does not happen on other devices on the bus. For instance, in the device with id 0x4F, the right values are printed: tw=>i2c md 4F 0.2 6 0000: 18 00 f6 48 00 00 ...H.. The address in the previous command has a ".2" because the chip uses 2 bytes for addresses. The first device only uses 1, so there's no need to put a ".1" (I already tested that). I went through the implementation of the Freescale driver for the I2C communication, but I didn't change anything on it and it works for other devices. My coworker also says that the very same code works on his board. Have anybody had a similar issue or has any theory about why this is happening? Thanks in advance.

This patch add Marvell kirkwood MVSDIO/MMC driver and enable it for Sheevaplugs and OpenRD boards. Signed-off-by: Gerald Kerma <drEagle(a)doukki.net> --- Changes in v5: - purge uneeded code - remove some extra debug Changes in v4: - rename drivers files to MVSDIO - fix MMC clock init which now use dev ID - clean debug strings - remove MVSDIO_TWEAK_NOSDHS quirk - remove dead code Changes in v3: - Add MVSDIO_TWEAK_NOSDHS quirk - Minor clean Changes in v2: - Fix some typo and missing lines from patch import arch/arm/include/asm/arch-kirkwood/kirkwood.h | 1 + board/Marvell/openrd/openrd.c | 11 + board/Marvell/sheevaplug/sheevaplug.c | 11 + drivers/mmc/Makefile | 1 + drivers/mmc/mvsdio.c | 353 ++++++++++++++++++++++++++ include/configs/openrd.h | 8 + include/configs/sheevaplug.h | 17 +- include/mvsdio.h | 279 ++++++++++++++++++++ 8 files changed, 679 insertions(+), 2 deletions(-) create mode 100644 drivers/mmc/mvsdio.c create mode 100644 include/mvsdio.h diff --git a/arch/arm/include/asm/arch-kirkwood/kirkwood.h b/arch/arm/include/asm/arch-kirkwood/kirkwood.h index bc207f5..3ea51d7 100644 --- a/arch/arm/include/asm/arch-kirkwood/kirkwood.h +++ b/arch/arm/include/asm/arch-kirkwood/kirkwood.h @@ -39,6 +39,7 @@ #define KW_EGIGA0_BASE (KW_REGISTER(0x72000)) #define KW_EGIGA1_BASE (KW_REGISTER(0x76000)) #define KW_SATA_BASE (KW_REGISTER(0x80000)) +#define KW_SDIO_BASE (KW_REGISTER(0x90000)) /* Kirkwood Sata controller has two ports */ #define KW_SATA_PORT0_OFFSET 0x2000 diff --git a/board/Marvell/openrd/openrd.c b/board/Marvell/openrd/openrd.c index a005a2f..6e9dca6 100644 --- a/board/Marvell/openrd/openrd.c +++ b/board/Marvell/openrd/openrd.c @@ -17,6 +17,9 @@ #include <asm/arch/kirkwood.h> #include <asm/arch/mpp.h> #include "openrd.h" +#ifdef CONFIG_MVSDIO_MMC +# include <mvsdio.h> +#endif /* CONFIG_MVSDIO_MMC */ DECLARE_GLOBAL_DATA_PTR; @@ -159,3 +162,11 @@ void reset_phy(void) #endif } #endif /* CONFIG_RESET_PHY_R */ + +#ifdef CONFIG_MRVL_MMC +int board_mmc_init(bd_t *bis) +{ + mrvl_mmc_init(bis); + return 0; +} +#endif /* CONFIG_MRVL_MMC */ diff --git a/board/Marvell/sheevaplug/sheevaplug.c b/board/Marvell/sheevaplug/sheevaplug.c index 87e49f4..c33f55c 100644 --- a/board/Marvell/sheevaplug/sheevaplug.c +++ b/board/Marvell/sheevaplug/sheevaplug.c @@ -12,6 +12,9 @@ #include <asm/arch/kirkwood.h> #include <asm/arch/mpp.h> #include "sheevaplug.h" +#ifdef CONFIG_MVSDIO_MMC +# include <mvsdio.h> +#endif /* CONFIG_MVSDIO_MMC */ DECLARE_GLOBAL_DATA_PTR; @@ -131,3 +134,11 @@ void reset_phy(void) printf("88E1116 Initialized on %s\n", name); } #endif /* CONFIG_RESET_PHY_R */ + +#ifdef CONFIG_MRVL_MMC +int board_mmc_init(bd_t *bis) +{ + mrvl_mmc_init(bis); + return 0; +} +#endif /* CONFIG_MRVL_MMC */ diff --git a/drivers/mmc/Makefile b/drivers/mmc/Makefile index 34febf5..1c8f275 100644 --- a/drivers/mmc/Makefile +++ b/drivers/mmc/Makefile @@ -37,3 +37,4 @@ obj-$(CONFIG_SPL_MMC_BOOT) += fsl_esdhc_spl.o else obj-$(CONFIG_GENERIC_MMC) += mmc_write.o endif +obj-$(CONFIG_MVSDIO_MMC) += mvsdio.o diff --git a/drivers/mmc/mvsdio.c b/drivers/mmc/mvsdio.c new file mode 100644 index 0000000..3139526 --- /dev/null +++ b/drivers/mmc/mvsdio.c @@ -0,0 +1,353 @@ +/* + * Marvell MMC/SD/SDIO driver + * + * (C) Copyright 2012 + * Marvell Semiconductor <www.marvell.com> + * Written-by: Maen Suleiman, Gérald Kerma + * + * SPDX-License-Identifier: GPL-2.0+ + */ + +#include <common.h> +#include <malloc.h> +#include <part.h> +#include <mmc.h> +#include <asm/io.h> +#include <asm/arch/cpu.h> +#include <asm/arch/kirkwood.h> + +#include <mvsdio.h> + +#define DRIVER_NAME "MVSDIO" + +#define mvsd_write(offs, val) writel(val, CONFIG_SYS_MMC_BASE + (offs)) +#define mvsd_read(offs) readl(CONFIG_SYS_MMC_BASE + (offs)) + +#define MRVL_MMC_MAKE_CMD(c, f) (((c & 0xff) << 8) | (f & 0xff)) + +static int mrvl_mmc_setup_data(struct mmc_data *data) +{ + u32 ctrl_reg; + + debug("%s, data %s : blocks=%d blksz=%d\n", DRIVER_NAME, + (data->flags & MMC_DATA_READ) ?

[U-Boot] [PATCH] arm: mx5: Fix RTC bus number
by Marek Vasut 25 Jul '14

A previous update to the I2C stack introduced a typo in the configuration option. Fix the typo and therefore allow the RTC to work correctly with the 'date' command again.

[U-Boot] [PATCH] powerpc/T4240QDS/eth: fix for XFI
by shh.xie＠gmail.com 25 Jul '14

25 Jul '14

From: Shaohui Xie <Shaohui.Xie(a)freescale.com> XFI is supported on T4QDS-XFI board, which removed slot3, and four LANEs of serdes2 are routed to a SFP+ cages, which to house fiber cable or direct attach cable(copper), the copper cable is used to emulate the 10GBASE-KR scenario. So, for XFI usage, there are two scenarios, one will use fiber cable, another will use copper cable. For fiber cable, there is NO PHY, while for copper cable, we need to use internal PHY which exist in Serdes to do auto-negotiation and link training, which implemented in kernel. We use hwconfig to define cable type for XFI, and fixup dtb based on the cable type. For copper cable, set below env in hwconfig: fsl_10gkr_copper:<10g_mac_name> the <10g_mac_name> can be fm1_10g1, fm1_10g2, fm2_10g1, fm2_10g2. The four <10g_mac_name>s do not have to be coexist in hwconfig. For XFI ports, if a given 10G port will use the copper cable for 10GBASE-KR, set the <10g_mac_name> of the port in hwconfig, otherwise, fiber cable will be assumed to be used for the port. For ex. if four XFI ports will both use copper cable, the hwconfig should contain: fsl_10gkr_copper:fm1_10g1,fm1_10g2,fm2_10g1,fm2_10g2 For fiber cable: 1. give PHY address to a XFI port, otherwise, the XFI ports will not be available in U-boot, there is no PHY physically for XFI when using fiber cable, this is just to make U-boot happy and we can use the XFI ports in U-boot. 2. fixup dtb to use fixed-link in case of fiber cable which has no PHY. Kernel requests that a MAC must have a PHY or fixed-link.
