* 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>

* microblaze: avoid interrupt race conditionsStephan Linz2012-02-23-2/+2
| | | | | | | | | | | | | | The interrupt acknowledge action have to run after the registered interrupt handler. So we have a chance to bear out the corresponding interrupt request in the corresponding controller hardware. With this reordering, we optain a proper interrupt handling for level triggered interrupt sources -- for example the new axi_timer v1.02.a introduced in ISE 13.2.

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.

By adding the linear address (i.e. the 'D' segment address) as the first word of the global data structure, the address of the global data relative to the 'D' segment can be found simply, for example, by: fs movl 0, %eax This makes the gd 'pointer' writable prior to relocation (by reloading the Global Desctriptor Table) which brings x86 into line with all other arches NOTE: Writing to the gd 'pointer' is expensive (but we only do it twice) but using it to access global data members (read and write) is still fairly cheap -- Changes for v2: - Rebased against changes made to patch #3 - Removed extra indent - Tweaked commit message
