* blackfin: Correct early serial mess output in BYPASS boot mode.Sonic Zhang2013-05-13-3/+27
| | | | | | | | | | | | The early serial should not be configured again in initcode() for BYPASS boot mode and in start() for the other LDR boot modes. In BYPASS boot mode, the start up code is located in Nor flash address other than the DRAM address defined in link script. The code embedded string can't be addressed by its compile time symbol. Calculate it according to the flash offset. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com>

* Blackfin: adjust asm constraints with NMI workaroundMike Frysinger2013-05-13-1/+2
| | | | | | | | | | | | | | | | | | | | | Newer gcc versions will sometimes use a Preg when "r" constraints, but that'll fail if we use an Ireg in the assignment. So force the code to always use a Dreg. This also fixes early boot crashes for older Blackfin parts when compiled with gcc-4.5. This version ends up selecting the same register for the input and output variables which corrupts the output assignment triggering an exception.

* gpio: Add support for microblaze xilinx GPIOMichal Simek2013-05-09-39/+386
| | | | | | | | | | | | | | | | | | | | | | | | Microblaze uses gpio which is connected to the system reset. Currently gpio subsystem wasn't used for it.

| * mmc: Split device init to decouple OCR-polling delayChe-Liang Chiou2013-05-06-32/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of time that MMC driver spends on initializing a device is polling OCR (operation conditions register). To decouple this polling loop, device init is split into two parts: The first part fires the OCR query command, and the second part polls the result. So the caller is now no longer bound to the OCR-polling delay; he may fire the query, go somewhere and then come back later for the result. To use this, call mmc_set_preinit() on any device which needs this. This can save significant amounts of time on boot (e.g. 200ms) by hiding the MMC init time behind other init.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Hydra and Superhydra (P3041DS, P5020DS, and P5040DS) boards have a second USB port that can be configured in either host, peripheral (aka device), or OTG (on-the-go) mode. When configured in host mode, if the port is connected to another USB host, damage to the board can occur. To avoid this, we change the default setting to peripheral mode. Ideally, we'd set it to OTG mode, but currently there is no OTG support for these boards. Setting the hwconfig variable will also update the device tree, and so Linux will configure the port for peripheral mode as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When P1021RDB-PC reboot system, the board will hung at uboot DDR configuration. For P1021RDB-PC DDR reset pin is multiplex with QE, so uboot will reserve this pin for QE and skip DDR reset. Other platforms without QE will do this reset. This patch adds a slight code to reset DDR chip by QE CE_PB8 pin for NAND and NOR FLASH boot. For booting from SPI FALSH and SD card, it seems possible to use the rom on chip to write to the GPIO pins before configuring the DDR.
