* mxc_spi: Round up clock dividerBenoît Thébaudeau2012-09-01-2/+2
| | | | | | | | | | | Since the input frequency of the API is a maximum that should not be exceeded in order for the devices to operate properly, the SPI clock divider should be rounded up, not truncated.

* ARM: add basic support for the Broadcom BCM2835 SoCStephen Warren2012-09-01-0/+90
| | | | | | | | | | | | | | | | | This SoC is used in the Raspberry Pi, for example. For more details, see: http://www.broadcom.com/products/BCM2835 http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf. Initial support is enough to boot to a serial console, execute a minimal set of U-Boot commands, download data over a serial port, and boot a Linux kernel. No storage or network drivers are implemented. GPIO driver originally by Vikram Narayanan <vikram186@gmail.com> with many fixes from myself. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

* arm: omap: Fix switching back to nandecc sw.Jeroen Hofstee2012-09-01-0/+1
| | | | | | | | | | | | | | | | | | | | | | Orjan Friberg wrote at [1]: "For the beagleboard, ecc.size is not explicitly set when doing 'nandecc sw'. If it's not set for the NAND_ECC_SOFT case in nand_scan_tail, it's set to 256 bytes. When doing 'nandecc hw', ecc.size is set to 512 bytes. Hence, when changing back to 'nandecc sw' ecc.size remains at 512 bytes and suddenly the format has changed." No patch has been submitted and the issue was still present. This patch adds the mentioned solution. Tested on a tam3517 board.

| | | | | | | | | | | | | | | | | The DMA transfers happen only if the transfered data are larger than 512 bytes. Otherwise PIO is used. This is a small speed optimization. The DMA transfer doesn't work if unaligned transfer is requested due to the limitation of the DMA controller. This has to be fixed by introducing generic bounce buffer. Therefore the DMA feature is now disabled by default.

I've tested it with EEPROM (16 bit address) and TPS65217 chip (8 bit address) on TI Beaglebone board.

| * I2C: Modify the I2C driver for EXYNOS5Rajeshwari Shinde2012-07-31-77/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies the S3C I2C driver to suppport EXYNOS5. The cahnges made to driver are as follows: - I2C base address is passed as a parameter to many functions to avoid multiple #ifdef - Channel initialisation is moved to a commom funation as it is required by i2c_init. - Hardcoding for I2CCON_ACKGEN removed. - Replaced printf with debug. - Checkpatch issues resolved. - Pinmux setting will be done in board/samsung/smdk5250/smdk5250.c to avoid repeated setting of gpio lines, as it have multi bus support.
