2013-05-13blackfin: Move blackfin watchdog driver out of the blackfin arch folder.Sonic Zhang
- Enable hw_watchdog_init() in watchdog.h if CONFIG_HW_WATCHDOG is defined. - Move blackfin hw watchdog driver to the generic driver folder. - Call hw_watchdog_init() from blackfin board init code. - Reuse macro CONFIG_WATCHDOG_TIMEOUT_MSECS - Update README.watchdog accordingly Signed-off-by: Sonic Zhang <sonic.zhang@analog.com>

2013-05-13blackfin: Enable early print via the generic serial API.Sonic Zhang
Remove blackfin specific implementation of the generic serial API when early print macro is defined. In BFIN_BOOT_BYPASS mode, don't call generic serial_puts, because early print in bypass mode is running before code binary is relocated to the link address.

2013-05-13blackfin: Correct early serial mess output in BYPASS boot mode.Sonic Zhang
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>

2013-05-13Blackfin: adjust asm constraints with NMI workaroundMike Frysinger
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.

2013-05-09gpio: Add support for microblaze xilinx GPIOMichal Simek
Microblaze uses gpio which is connected to the system reset. Currently gpio subsystem wasn't used for it. Add gpio driver and change Microblaze reset logic to be done via gpio subsystem. There are various configurations which Microblaze can have that's why gpio_alloc/gpio_alloc_dual(for dual channel) function has been introduced and gpio can be allocated dynamically. Adding several gpios IP is also possible and supported.

2013-05-06mmc: Split device init to decouple OCR-polling delayChe-Liang Chiou
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.

Untill now we power-cycle (aka: disable power on a port and re-enabling again) one port at a time. Delay of 20ms for Port-power to change multiplies with number of ports in this case. So better we parallelize this process: disable power on all ports, wait for port-power to stabilize and then re-enable the power subsequently. Signed-off-by: Vivek Gautam <gautam.vivek@samsung.com>

Patch b6d7852c increases timeout for enumeration, taking worst case to be 10 sec. get_timer() api returns timestamp in milliseconds, which is what we are checking in the do-while() loop in usb_hub_configure() (get_timer(start) < CONFIG_SYS_HZ * 10).
