[U-Boot] [PATCH] lpc32xx: remove surplus clock cycle in PL175 WAIT_OEN config
by Vladimir Zapolskiy 12 Oct '15

12 Oct '15

According to ARM PrimeCell PL175 documentation WAIT_OEN config value is defined without any additional clocks added to the value set by a client, the change fixes the wrong interface to WAIT_OEN config. The change also touches a single user of LPC32xx EMC and corrects configured "output enable delay" value on its side according to the changed interface. No functional change intended.

[U-Boot] [PATCH] nand: omap_gpmc: Change correctable bit-flips messages to debug()
by Ezequiel Garcia 12 Oct '15

Messages on corrected bit-flips are not really useful, as bit-flips are perfectly normal. Let's avoid cluttering the console and make them debug.

[U-Boot] [PATCH] Fix variation in timestamps caused by timezone differences.
by Vagrant Cascadian 12 Oct '15

12 Oct '15

When building with SOURCE_DATE_EPOCH set, avoid use of mktime in default_image.c, which converts the timestamp into localtime. This causes variation based on timezone when building u-boot.img and u-boot-sunxi-with-spl.bin targets.

[U-Boot] [PATCH] arndale: Apply Cortex-A15 errata #773022 and #774769
by Ian Campbell 12 Oct '15

12 Oct '15

We run 4 Arndale boards in our automated test framework, they have been running quite happily for quite some time using a Debian Wheezy userspace. However when upgrading to a Debian Jessie we started seeing frequent segmentation faults from gcc when building the kernel, to the extent that it is unable to successfully build the kernel twice in a row, and often fails on the first attempt. Searching around I found https://bugs.launchpad.net/arndale/+bug/1081417 which pointed towards http://www.spinics.net/lists/kvm-arm/msg03723.html and CPU Errata 773022 and 774769. This errata needs to be applied to all processors in an SMP system, meaning that the usual strategy of applying them in arch/arm/cpu/armv7/start.S is not appropriate (since that applies to the boot processor only). Instead we apply these errata in the secure monitor which is code that is traversed by all processors as they are brought up. The net affect on Arndale is that ACTLR changes from 0x40 to 0x2000042. I ran 17 kernel compile iterations overnight with no segfaults. Runtime testing was done on our v2014.10 based branch and forward ported (with only minimal and trivial contextual conflicts) to current master, where it has been build tested only. I suppose in theory these errata apply to any Exynos5250 based boards, but Arndale is the only one I have access to and I have therefore chosen to be conservative and only apply it there. Also, reorder CONFIG_ARM_ERRATA_794072 in README to make the list numerically sorted.

[U-Boot] fatwrite problem
by Ruud Commandeur 12 Oct '15

12 Oct '15

Hi Everyone, Sinced a few days I noticed some problems writing the uimage to a FAT partition on my SD-card. At first I was afraid of some (physical) SD-card problems, but it appears to be related to he size of the uImage. With some further testing (and adding some debug printing), I could easily reproduce the problem: //4K file, result OK fatwrite mmc 0:1 42000000 testfile 1000 writing testfile set_cluster; clustnum: 5, startsect: 176, size 2048 set_cluster; clustnum: 6, startsect: 180, size 2048 set_cluster; clustnum: -6, startsect: 132, size 2048 4096 bytes written //512 bytes file, timeout error, file not written fatwrite mmc 0:1 42000000 testfile 200 writing testfile set_cluster; clustnum: 5, startsect: 176, size 0 MMC0: Bus busy timeout! MMC0: Bus busy timeout! MMC0: Bus busy timeout! MMC0: Bus busy timeout! MMC0: Bus busy timeout! MMC0: Bus busy timeout! set_cluster; clustnum: 5, startsect: 176, size 512 MMC0: Bus busy timeout! MMC0: Bus busy timeout! MMC0: Bus busy timeout! set_cluster; clustnum: -6, startsect: 132, size 2048 MMC0: Bus busy timeout! 512 bytes written It seems to be related to he problem reported here: http://www.mail-archive.com/u-boot@lists.denx.de/msg107212.html Once the size of the set_cluster call equals 0, the mmc command is incomplete and times out. In the earlier reported problem, a patch is mentioned, but not available for dowload here. Also in the latest versions of the git repository I could not find a patch for this problem. Can anyone tell me if there is a fix for this problem? Regards, Ruud

[U-Boot] [PATCH] common/image.c: Make boot_get_ramdisk() perform a check for Android images
by Tom Rini 12 Oct '15

12 Oct '15

In 2dd4632 the check for where a ramdisk is found on an Android image was got moved into the "normal" loop here, causing people to have to pass the kernel address in the ramdisk address location in order to have Android boot still. This changed previous behavior so perform a check early in the function to see if we have an Android image and if so use that as where to look for the ramdisk (which is what the rest of the code here expects).

Yah, this sound good to me where user can use DT variant if concern about the boot time. Let me create that and sending in new revision. Thanks Chin Liang
