[U-Boot] [PATCH] At start of autoboot check, flush any pending RX bytes
by Craig McQueen 20 Jan '16

20 Jan '16

This is to avoid the boot sequence halting due to initial "junk" received on serial input. Signed-off-by: Craig McQueen <craig.mcqueen(a)innerrange.com> --- I have found that on the BeagleBone Black, U-Boot occasionally halts at the U-Boot prompt at boot-up, whether power-up, warm external reset or software reset. I have seen other people report the same issue. This seems to be due to U-Boot receiving "junk" data on the serial console. The BeagleBone Black has a pull-down resistor which was apparently added to try to mitigate this issue, but it doesn't entirely fix it. common/autoboot.c | 20 +++++++++++++++----- 1 file changed, 15 insertions(+), 5 deletions(-) diff --git a/common/autoboot.c b/common/autoboot.c index c11fb31..3ab51d9 100644 --- a/common/autoboot.c +++ b/common/autoboot.c @@ -230,19 +230,29 @@ static int abortboot_normal(int bootdelay) printf("Hit any key to stop autoboot: %2d ", bootdelay); #endif -#if defined CONFIG_ZERO_BOOTDELAY_CHECK /* - * Check if key already pressed - * Don't check if bootdelay < 0 + * Flush any pending input key presses. + * On some systems, there might be some junk input. + * No need if bootdelay < 0. */ if (bootdelay >= 0) { - if (tstc()) { /* we got a key press */ + ts = get_timer(0); + while (tstc()) { /* we got a key press */ (void) getc(); /* consume input */ +#if defined CONFIG_ZERO_BOOTDELAY_CHECK puts("\b\b\b 0"); abort = 1; /* don't auto boot */ + break; +#else + /* + * Sanity check just to avoid infinite loop.

[U-Boot] Chain-loading u-boot stopped working between 2016.01-rc1 and 2016.01-rc4
by Pavel Machek 20 Jan '16

20 Jan '16

Hi! I'm loading u-boot using tftp from u-boot 2013.01. Marek will claim that this configuration is unsupported, but it enables fairly quick development and was very useful for me in past. Unfortunately, it stopped working between 2016.01-rc1 and -rc4. Before I start bisecting it, I wanted to ask if someone has idea what might be responsible?

[U-Boot] [PATCH] wandboard: fix variable name so PXE boot works
by Peter Robinson 20 Jan '16

20 Jan '16

All boards that support PXE booting use the pxefile_addr_r variable. Standardise wandboard with this variable as pxe_addr_r isn't used anywhere else so it's a typo.

[U-Boot] [PATCH 1/3] vsprintf.c: Always enable CONFIG_SYS_VSNPRINTF
by Tom Rini 20 Jan '16

20 Jan '16

Enabling this function always removes some class of string saftey issues. The size change here in general is about 400 bytes and this seems a reasonable trade-off. Cc: Peng Fan <peng.fan(a)nxp.com> Cc: Peter Robinson <pbrobinson(a)gmail.com> Cc: Fabio Estevam <fabio.estevam(a)freescale.com> Cc: Adrian Alonso <aalonso(a)freescale.com> Cc: Stefano Babic <sbabic(a)denx.de> Cc: Hans de Goede <hdegoede(a)redhat.com> Signed-off-by: Tom Rini <trini(a)konsulko.com> --- I ran my usual world build of buildman with size comparison options this time to test this out. The only exception to the general size change here are q8_a23_tablet_800x480 and gt90h_v4 both in the non-SPL case. These both grow by 3780 bytes in the non-SPL case. In all cases except those two, when paired with the gzwrite patch I posted yesterday we gain all of that back, or more. --- README | 9 --------- configs/bayleybay_defconfig | 1 - configs/chromebook_link_defconfig | 1 - configs/chromebox_panther_defconfig | 1 - configs/coreboot-x86_defconfig | 1 - configs/crownbay_defconfig | 1 - configs/galileo_defconfig | 1 - configs/minnowmax_defconfig | 1 - configs/qemu-x86_defconfig | 1 - configs/sandbox_defconfig | 1 - include/vsprintf.h | 12 ------------ lib/Kconfig | 9 --------- lib/vsprintf.c | 12 ------------ 13 files changed, 51 deletions(-) diff --git a/README b/README index 5ac2d44..b7ce63d 100644 --- a/README +++ b/README @@ -890,15 +890,6 @@ The following options need to be configured: 'Sane' compilers will generate smaller code if CONFIG_PRE_CON_BUF_SZ is a power of 2 -- Safe printf() functions - Define CONFIG_SYS_VSNPRINTF to compile in safe versions of - the printf() functions.

This has been tested on the following evms (logs [1]) by loading kernel and dtb from sata hard-disk. * dra72 evm * dra74 evm Also pushed a branch for testing [2] [1] - http://pastebin.ubuntu.com/14565924/ [2] - git://git.ti.com/~mugunthanvnm/ti-u-boot/mugunth-ti-u-boot.git dm-sata Mugunthan V N (6): arm: omap: sata: move enable sata clocks to enable_basic_clocks() dm: implement a SATA uclass arm: omap-common: sata: prepare driver for DM conversion drivers: block: dwc_ahci: Implement a driver for Synopsys DWC sata device defconfig: dra74_evm: enable sata driver model defconfig: dra72_evm: enable sata driver model arch/arm/cpu/armv7/omap-common/sata.c | 38 ++++++------------- arch/arm/cpu/armv7/omap5/hw_data.c | 12 ++++++ configs/dra72_evm_defconfig | 2 + configs/dra74_evm_defconfig | 2 + drivers/block/Kconfig | 17 +++++++++ drivers/block/Makefile | 3 ++ drivers/block/dwc_ahci.c | 71 +++++++++++++++++++++++++++++++++++ drivers/block/sata-uclass.c | 69 ++++++++++++++++++++++++++++++++++ include/dm/uclass-id.h | 1 + include/sata.h | 2 + 10 files changed, 190 insertions(+), 27 deletions(-) create mode 100644 drivers/block/dwc_ahci.c create mode 100644 drivers/block/sata-uclass.c -- 2.7.0.rc3

[U-Boot] [Patch V4 2/4] spi: fsl_qspi: Fix qspi_op_rdid memcpy issue
by Gong Qianyu 20 Jan '16

20 Jan '16

From: Gong Qianyu <Qianyu.Gong(a)freescale.com> In current driver everytime we memcpy 4 bytes to the dest memory regardless of the remaining length. This patch adds checking the remaining length before memcpy. If the length is shorter than 4 bytes, memcpy the actual length of data to the dest memory.
