2012-09-02rtc: pcf8563: Make century compatible with LinuxBenoît Thébaudeau
This driver uses the century bit of this RTC in the opposite way Linux does. From Linux's rtc-pcf8563.c: /* * The meaning of MO_C bit varies by the chip type. * From PCF8563 datasheet: this bit is toggled when the years * register overflows from 99 to 00 * 0 indicates the century is 20xx * 1 indicates the century is 19xx * From RTC8564 datasheet: this bit indicates change of * century. 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. So let's do it heuristically, assuming we are live in * 1970...2069. */ As U-Boot's PCF8563 driver does not say it is supposed to support the RTC8564, make this driver compatible with Linux's by giving the opposite meaning to the century 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. That way, u-boot can just read what's there and get on with life. This is what SeaBIOS does. Signed-off-by: Andrew Sharp <andywyse6@gmail.com>
2012-09-02pci: minor cleanup of CONFIG_PCI_PNP usageAndrew Sharp

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>

2012-09-01ehci-hcd: Boost transfer speedBenoît Thébaudeau
This patch takes advantage of the hardware EHCI qTD queuing mechanism to avoid software and transfer splitting overhead so as to make transfers as fast as possible. The only drawback is a call to memalign. However, this is fast compared to the transfer timings, and the heap size to allocate is small, e.g. 128 kiB in the worst case for a transfer length of 65535 packets of 512 bytes. Tested on i.MX25, i.MX35 and i.MX51. In my test conditions, the speed gain was very significant (several times faster), which is really appreciable when accessing large files.

The cache snooping feature of Freescale's eSDHC IP is not available on i.MX, so disable it globally for this architecture. This avoids setting no_snoop for all i.MX boards, and it prevents setting a reserved bit of a reserved register if fsl_esdhc_mmc_init() is used on i.MX, like in arch/arm/cpu/armv7/imx-common/cpu.c/cpu_mmc_init().

2012-09-01spi: fix mxs_spi_slave structure allocation to clear memoryMatt Sealey
Use calloc() instead of malloc() to allocate the mxs_spi_slave structure. Clearing the memory is necessary since most of the time this gets done super early in boot, but on warm reboots, and when SPI probing is done long after the init stages it could actually pick up previously used memory, and things like the chipselect polarity and other data end up being filled with trash data if not explicitly set by the board files. This solves a semi-random, almost unreproducable error whereby SPI devices act very, very strangly on boot. Signed-off-by: Matt Sealey <matt@genesi-usa.com> Acked-by: Stefano Babic <sbabic@denx.de>
