2012-09-17mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driverMarek Vasut
This is based on Linux kernel -next: commit 14f44abf1dafc20ba42ce8616a8fc8fbd1b3712b Author: Brian Norris <computersforpeace@gmail.com> Date: Fri Jul 13 09:28:24 2012 -0700 mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It silently masks off at least one flag that might be set by the driver (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly others. Really, as long as driver writers exercise a small amount of care with NAND_* options, this mask is not necessary at all; it was only here to prevent certain options from accidentally being set by the driver. But the original thought turns out to be a bad idea occasionally. Thus, kill it. Note, this patch fixes some major gpmi-nand breakage.

2012-09-05mmc: detect boot sectors using EXT_CSD_BOOT_MULT tooStephen Warren
Some eMMC devices contain boot partitions, but do not set the PART_SUPPORT bit in EXT_CSD_PARTITIONING_SUPPORT. Allow partition selection on such devices, by enabling partition switching when EXT_CSD_BOOT_MULT is set. Note that the Linux kernel enables access to boot partitions solely based on the value of EXT_CSD_BOOT_MULT; EXT_CSD_PARTITIONING_SUPPORT only influences access to "general" partitions. eMMC devices affected by this issue exist on various NVIDIA Tegra platforms (and presumably many others too), such as Harmony (plug-in eMMC), Seaboard, Springbank, and Whistler (plug-in eMMC).

When the year digit data overflows from 99 to 00, * this bit is set. By presetting it to 0 while still in the * 20th century, it will be set in year 2000, ... * There seems no reliable way to know how the system use this * bit.

2012-09-02pci: add CONFIG_PCI_ENUM_ONLY for platforms that don't need PCI setup doneAndrew Sharp
Introduce CONFIG_PCI_ENUM_ONLY variable for platforms that just want a quick enumberation of the PCI devices, but don't need any setup work done. This is very beneficial on platforms that have u-boot loaded by another boot loader which does a more sophisticated job of setup of PCI devices than u-boot.

2012-09-01at91: atmel_nand: Update driver to support Programmable Multibit ECC controllerWu, Josh
The Programmable Multibit ECC (PMECC) controller is a programmable binary BCH(Bose, Chaudhuri and Hocquenghem) encoder and decoder. This controller can be used to support both SLC and MLC NAND Flash devices. It supports to generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector of data. To use PMECC in this driver, the user needs to set the PMECC correction capability, the sector size and ROM lookup table offsets in board config file. This driver is ported from Linux kernel atmel_nand PMECC patch. The main difference is in this version it uses registers structure access hardware instead of using macros. It is tested in 9x5 serial boards. Signed-off-by: Josh Wu <josh.wu@atmel.com> [rebase] Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
