* mx6q: mx6qsabrelite: Conditionally define macros for environment in serial flashEric Nelson2012-02-27-3/+15
| | | | | | | | | | | | | | | | | | | | | | The default settings store the persistent environment on SD card and not serial flash (SPI NOR). To use SPI NOR to save the environment instead of SD card, edit include/configs/mx6qsabrelite.h and - undefine CONFIG_ENV_IS_IN_MMC - define CONFIG_ENV_IS_IN_SPI_FLASH The SPI driver can take as chip select the controller's chip selects as well as an external GPIO. The LSB byte has the value of the internal chip select, the highest (thought as 16-bit value) contains the GPIO number. The GPIO used on Sabre Lite is GP3:19 == 83.

* mx6q: define GPIO macros for translating between ordinals and port:indexEric Nelson2012-02-27-0/+4
| | | | | | | | | | | | | | | | | The interface to the mxc_gpio driver uses integer (ordinal) values to refer to all GPIOs on the i.MX processors. The registers themselves and much of the i.MX documentation are banked in groups of 32, and these macros allow the use of the port:index numbering for clarity. GPIO_NUMBER() converts to ordinal value from port:index GPIO_PORT() returns the port of an ordinal value GPIO_INDEX() returns the index or offset of the ordinal.

* mx28: fix SPL code to make USB booting workMatthias Fuchs2012-02-27-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes booting i.MX28 CPUs via USB download. In this mode the CPU's bootrom implements a USB HID device that accepts a bootstream. When downloading the bootstream via USB, first the SPL code is received and executed. Then the u-boot image is received and called. The USB bootmode is interrupt driven. This patch fixes two things: 1) The ARM's fast interrupt mode is disabled when the SPL code has been run. So save and restore the CPSR register. 2) Save and restore c1 control register: the exception vector location needs to be set back to bootrom space to make the USB interrupts work again. The SPL code needs to change this option for the ram size probing. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd.eu> Acked-by: Marek Vasut <marek.vasut@gmail.com>

| * mmc: fix card busy pollingJan Kloetzke2012-02-15-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | A MMC/SD card may always go into the programming state (and hence be busy) after a block write. Therefore always check the card state, even after single block writes. On the other hand there is no need to check the card status after a read. Also make sure that errors during busy polling are propagated upwards. Signed-off-by: Jan Kloetzke <jan.kloetzke@dspg.com> Cc: Andy Fleming <afleming@gmail.com>
| * Tegra: mmc: Fixed handling of interrupts in timeouts.Tom Warren2012-02-15-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | We are seeing occasional timeouts in the Tegra mmc code when we are reading from external MMC cards. These don't seem to be detrimental if they are handled properly. This CL properly clears the "normal interrupt status register" (norintsts) in error conditions. If we don't do this, when we come back into mmc_send_cmd() the register will still contain status from the last transaction.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before we can send a command we need both the DATI (command inhibit on mmc_dat line) bit and CMDI (command inhibit on mmc_cmd line) are clear. The previous behavior of only checking on DATI was insufficient on some cards and incorrect behavior in any case. This makes the code check for both bits being clear and makes the error print more clear as to what happened. DATI_CMDDIS is removed as it was unused elsewhere in the code and stood for 'DATI is set, cmds are disabled still'. Fix originally spotted by Peter Bigot. Tested-by: Peter A.
