[U-Boot] [PATCH V6] sf: Add clear flag status register operation support
by Zhiqiang Hou 18 Aug '15

18 Aug '15

From: Hou Zhiqiang <B48286(a)freescale.com> The clear flag status register operation was required by Micron SPI flash chips, which support FSR. And if an error bit of FSR have been set, it must be cleared by the clear FSR operation. Signed-off-by: Hou Zhiqiang <B48286(a)freescale.com> Signed-off-by: Mingkai.Hu <Mingkai.Hu(a)freescale.com> --- Tested on T1042RDB board. V6: Generate the patch based on the latest wait ready logic. Depend on patch http://patchwork.ozlabs.org/patch/508166/ V5: 1. Removed #ifdef for STMICRO. 2. Add checking Protection and Voltage error bits. 3. Only if there is any error bit set, issue the clear FSR command. V4: Split the the patch to 2 patches for clear FSR and SPI flash address mode. V3: Generate the patch based on the latest tree git://git.denx.de/u-boot.git. V2: Add the operation of enter 3 Byte address mode in probe. V1: Based on git://git.denx.de/u-boot.git. drivers/mtd/spi/sf_internal.h | 15 +++++++++++++++ drivers/mtd/spi/sf_ops.c | 7 +++++++ 2 files changed, 22 insertions(+) diff --git a/drivers/mtd/spi/sf_internal.h b/drivers/mtd/spi/sf_internal.h index 8a3e5ec..fc6d751 100644 --- a/drivers/mtd/spi/sf_internal.h +++ b/drivers/mtd/spi/sf_internal.h @@ -82,6 +82,7 @@ enum spi_nor_option_flags { #define CMD_WRITE_ENABLE 0x06 #define CMD_READ_CONFIG 0x35 #define CMD_FLAG_STATUS 0x70 +#define CMD_CLEAR_FLAG_STATUS 0x50 /* Read commands */ #define CMD_READ_ARRAY_SLOW 0x03 @@ -104,7 +105,15 @@ enum spi_nor_option_flags { #define STATUS_WIP (1 << 0) #define STATUS_QEB_WINSPAN (1 << 1) #define STATUS_QEB_MXIC (1 << 6) + +/* Flag status for STMICRO */ +#define STATUS_PROT_ERR (1 << 1) +#define STATUS_VOLT_ERR (1 << 3) +#define STATUS_PROG_ERR (1 << 4) +#define STATUS_ERASE_ERR (1 << 5) #define STATUS_PEC (1 << 7) +#define FLAG_ERR_MASK (STATUS_PROT_ERR | STATUS_VOLT_ERR | \ + STATUS_PROG_ERR | STATUS_ERASE_ERR) /* Flash timeout values */ #define SPI_FLASH_PROG_TIMEOUT (2 * CONFIG_SYS_HZ) @@ -191,6 +200,12 @@ static inline int spi_flash_cmd_write_disable(struct spi_flash *flash) return spi_flash_cmd(flash->spi, CMD_WRITE_DISABLE, NULL, 0); } +/* Clear flag status register */ +static inline int spi_flash_cmd_clear_flag_status(struct spi_flash *flash) +{ + return spi_flash_cmd(flash->spi, CMD_CLEAR_FLAG_STATUS, NULL, 0); +} + /* * Send the read status command to the device and wait for the wip * (write-in-progress) bit to clear itself. diff --git a/drivers/mtd/spi/sf_ops.c b/drivers/mtd/spi/sf_ops.c index ba5ff0c..78ef08b 100644 --- a/drivers/mtd/spi/sf_ops.c +++ b/drivers/mtd/spi/sf_ops.c @@ -174,6 +174,13 @@ static inline int spi_flash_fsr_ready(struct spi_flash *flash) if (ret < 0) return ret; + if (fsr & FLAG_ERR_MASK) { + printf("SF: flag status(0x%x) error occured\n", fsr); + ret = spi_flash_cmd_clear_flag_status(flash); + if (ret < 0) + printf("SF: clear flag status failed\n"); + return -1; + } return fsr & STATUS_PEC; } -- 2.1.0.27.g96db324

[U-Boot] [PATCH 1/2] RFT: arm: Switch 32-bit ARM to using generic global_data setup
by Simon Glass 18 Aug '15

18 Aug '15

There is quite a bit of assembler code that can be removed if we use the generic global_data setup. Less arch-specific code makes it easier to add new features and maintain the start-up code. Drop the unneeded code and adjust the hooks in board_f.c to cope.

[U-Boot] [PATCH 4/5] video: cfb_console: Allow VGA device to work without i8042 keyboard
by Bin Meng 18 Aug '15

18 Aug '15

So far if CONFIG_VGA_AS_SINGLE_DEVICE is not defined, the VGA device will try to initialize a keyboard device (for x86, it is i8042). But if i8042 controller initialization fails (eg: there is no keyboard connected to the PS/2 port), drv_video_init() just simply returns. This kills the opportunity of using a usb keyboard later with the vga concole, as the vga initialization part is actually ok, only keyboard part fails. Change the code logic to allow this. Signed-off-by: Bin Meng <bmeng.cn(a)gmail.com> --- In the long term, we should remove CONFIG_VGA_AS_SINGLE_DEVICE and treat the cfb_concole an output device only. The keyboard part should be moved out of cfb_console driver and be as a input device driver separately. drivers/video/cfb_console.c | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) diff --git a/drivers/video/cfb_console.c b/drivers/video/cfb_console.c index 30e0317..aa7ca86 100644 --- a/drivers/video/cfb_console.c +++ b/drivers/video/cfb_console.c @@ -2247,16 +2247,17 @@ __weak int board_video_skip(void) int drv_video_init(void) { - int skip_dev_init; struct stdio_dev console_dev; bool have_keyboard; + bool __maybe_unused keyboard_ok = false; /* Check if video initialization should be skipped */ if (board_video_skip()) return 0; /* Init video chip - returns with framebuffer cleared */ - skip_dev_init = (video_init() == -1); + if (video_init() == -1) + return 0; if (board_cfb_skip()) return 0; @@ -2272,11 +2273,9 @@ int drv_video_init(void) if (have_keyboard) { debug("KBD: Keyboard init ...\n"); #if !defined(CONFIG_VGA_AS_SINGLE_DEVICE) - skip_dev_init |= (VIDEO_KBD_INIT_FCT == -1); + keyboard_ok = !(VIDEO_KBD_INIT_FCT == -1); #endif } - if (skip_dev_init) - return 0; /* Init vga device */ memset(&console_dev, 0, sizeof(console_dev)); @@ -2287,7 +2286,7 @@ int drv_video_init(void) console_dev.puts = video_puts; /* 'puts' function */ #if !defined(CONFIG_VGA_AS_SINGLE_DEVICE) - if (have_keyboard) { + if (have_keyboard && keyboard_ok) { /* Also init console device */ console_dev.flags |= DEV_FLAGS_INPUT; console_dev.tstc = VIDEO_TSTC_FCT; /* 'tstc' function */ -- 1.8.2.1

[U-Boot] [PATCH 3/5] x86: i8042: Clean up the driver
by Bin Meng 18 Aug '15

18 Aug '15

This commit cleans up the existing i8042 driver by: - Reorder those static function so that their declarations can be removed - Remove unused routines i8042_flush() and i8042_disable() - Remove unused CONFIG_USE_CPCIDVI wrapped codes - Remove __weak board_i8042_skip() - Rename CamelCase variables to conform U-Boot coding convention - Rename wait_until_kbd_output_full() to kbd_output_full() - Change to use macros for i8042 command and control register bits Signed-off-by: Bin Meng <bmeng.cn(a)gmail.com> --- drivers/input/i8042.c | 633 +++++++++++++++++++++----------------------------- include/i8042.h | 112 +++++---- 2 files changed, 317 insertions(+), 428 deletions(-) diff --git a/drivers/input/i8042.c b/drivers/input/i8042.c index 3799580..3812733 100644 --- a/drivers/input/i8042.c +++ b/drivers/input/i8042.c @@ -10,49 +10,30 @@ /* includes */ #include <common.h> -#include <linux/compiler.h> -

[U-Boot] [PATCH 1/5] x86: superio: Add keyboard controller support to smsc_lpc47m driver
by Bin Meng 18 Aug '15

18 Aug '15

Add an api to enable and configure the integrated keyboard controller on SMSC LPC47m superio chipset. It also adds several macros to help future extension.
