[U-Boot] [PATCH] mx28evk: Disable CONFIG_CMD_I2C

From: Fabio Estevam <fabio.estevam(a)freescale.com> When loading a Freescale 2.6.35 on a mx28evk the following issue is seen: sgtl5000_hw_read: read reg error : Reg 0x00 Device with ID register 0 is not a SGTL5000 Disabling CONFIG_CMD_I2C makes the sgtl5000 probe to succeed.

[U-Boot] [PATCH] imx-common: timer: fix 32-bit overflow
by Dirk Behme 20 Mar '13

20 Mar '13

From: Knut Wohlrab <knut.wohlrab(a)de.bosch.com> The i.MX6 common timer uses the 32-bit variable tbl (time base lower) to record the overflow of the 32-bit counter. I.e. if the counter overflows, the variable tbl does overflow, too. To capture this overflow, use the variable tbu (time base upper), too. Return the combined value of tbl and tbu. lastinc is unused then, remove it.

Board:AT91SAM9G20 OS:Linux Soft Version:uboot 1.3.4 In u-boot/include/configs/at91sam9g20ek.h ,it had add #define CONFIG_CMD_USB and #define CONFIG_CMD_FAT but I use "usb start"cmd when my board run in uboot,it can not scan the usb storage,and print ERROR:CTL TIMEOUT how to solute.

Can I assume that is permitted? Without knowing the underlying mechanics of how that works, "maybe". And we already have malloc in SPL thanks to FAT support. -- Tom

[U-Boot] [PATCH 0/4 v7] Add ACE HW support for SHA256 and SHA1
by Akshay Saraswat 19 Mar '13

19 Mar '13

This patch set adds hardware acceleration for SHA 256 with the help of ACE. Changes since v1: - Patch-1: Fixed few nits. - Patch-2: Removed not required config. - Patch-3: Added sha256 to hash command instead of new sha256 command. Changes since v2: - Patch-1: - Added falling back to software sha256 in case length exceeds buffer limit. - Reduced one tab at lines 533, 559 and 571 in the patch. - Removed space after a cast at line 506 in the patch. - Removed blank line at line 561 in the patch. - Removed space before semicolon at line 576 in the patch. - Patch-2: - Added "SHA1" in the comment for config. - Patch-3: - Added new nodes for SHA1 and SHA256 in struct hash_algo for the case when ACE is enabled. - Added new declaration for function pointer hash_func_ws with different return type. - Patch-4: - New patch to enable config for hash command. Changes since v3: - Patch-1: - Removed buffer limit since there are 2 regs for address hash_msg_size_high and low. That means buffer length could go upto 2^64 bits which is practically - Removed falling back to software sha256 because there is no buffer limit. - Removed "/ 4" to sha1 and sha256 lengths and added increment to 4 in for loop at line 573. - Timed out still kept to be 100 ms since this is enough for hardware to switch status to idle from busy. In case it couldn't that means h/w is faulty. - Patch-2: - Added "Acked-by: Simon Glass <sjg(a)chromium.org>". - Patch-3: - New patch. - Patch-4: - Changed command names to lower case in algo struct. - Added generic ace_sha config. - Patch-5: Added acked-by Simon Glass - Added new generic config for ace_sha to enable ace support in hash.c. Changes since v4: - Patch-1: - Added include for clk.h. - Added define for MAX_FREQ. - Added timeout calculation as per frequency. - Changed "i+=4" to "i++" and "len" to "len/4" in for loop at line 591 in this patch. - Added two new functions ace_sha256 and ace_sha1. - Patch-2: None. - Patch-3: - Changed function names in struct algo. - Replaced ACE_SHA_TYPE to CHUNSZ in struct algo. - Patch-4: Added "Acked-by: Simon Glass <sjg(a)chromium.org>". Changes since v5: - Patch-1: - Removed ace_sha.h. - Renamed ace_sfr.h as ace_sha.h. - Removed timeout and checking for PRNG_ERROR bit in HASH_STATUS register. PRNG_ERROR bit high means setup was not done properly. Since there is no way to detect faulty h/w, we consider the possible fact that h/w should not be able to setup feed properly if it's faulty. - Renamed function name ace_sha256 to hw_sha256 and ace_sha1 to hw_sha1. - Patch-2: None. - Patch-3: - Added file hw_sha.h. - Changed CONFIG_ACE_SHA to CONFIG_SHA_HW_ACCEL. - Renamed function names ace_sha1 and ace_sha256 to hw_sha1 and hw_sha256 respectively. - Patch-4: - Removed "Acked-by: Simon Glass <sjg(a)chromium.org>" because of a change. - Changed CONFIG_ACE_SHA to CONFIG_SHA_HW_ACCEL. Changes since v6: - Patch-1: Added "Acked-by: Simon Glass <sjg(a)chromium.org>". - Patch-2: None. - Patch-3: - Changed position of "hw_sha.h" among includes (alpha order). - Rebased patch. - Patch-4: Added "Acked-by: Simon Glass <sjg(a)chromium.org>".

Albert has already accepted my PR a few days ago for ARM/master, so if these go into TOT u-boot.git from the USB tree, we'll have a conflict. Not to mention the fact that you appear to be missing a couple of Lucas' patches (6/7 tegra: use: move implementation into right directory & 7/7 tegra: usb: move [start|stop]_port into ehci_hcd_[init|stop]). I've also had these 7 patches marked as 'Accepted' in Patchwork for some time now. Please fix this.
