* e6500: Move L1 enablement after L2 enablementAndy Fleming2013-05-14-47/+47
| | | | | | | | | | The L1 D-cache on e6500 is write-through. This means that it's not considered a good idea to have the L1 up and running if the L2 is disabled. We don't actually *use* the L1 until after the L2 is brought up on e6500, so go ahead and move the L1 enablement after that code is done. Signed-off-by: Andy Fleming <afleming@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This timer runs at a rate that can be calculated, well over 100MHz. It is ideal for accurate timing and does not need interrupt servicing.

* | avr32: fix relocation address calculationAndreas Bießmann2013-05-13-2/+2
|/ | | | | | | | | | | | Commit 1865286466a5d0c7f2e3c37632da56556c838e9e (Introduce generic link section.h symbol files) changed the __bss_end symbol type from char[] to ulong. This led to wrong relocation parameters which ended up in a not working u-boot. Unfortunately this is not clear to see cause due to RAM aliasing we may get a 'half-working' u-boot then. Fix this by dereferencing the __bss_end symbol where needed. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>

* gpio: Add support for microblaze xilinx GPIOMichal Simek2013-05-09-33/+7
| | | | | | | | | | | | | | | | | | | | | | | | 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. For listing gpio configuration please use "gpio status" command This patch also remove one compilation warning: microblaze-generic.c: In function 'do_reset': microblaze-generic.c:38:47: warning: operation on '*1073741824u' may be undefined [-Wsequence-point] Signed-off-by: Michal Simek <michal.simek@xilinx.com>

* sandbox: Add CONFIG_OF_HOSTFILE to read FDT from host fileSimon Glass2013-05-01-0/+8
| | | | | | | | | | | | With sandbox it is tricky to add an FDT to the image at build time (or later) since we build an ELF file, not a plain binary, and the address space of the whole U-Boot is not accessible in the emulated memory map of sandbox.

* sandbox: Provide a way to map from host RAM to U-Boot RAMSimon Glass2013-05-01-0/+8
| | | | | | | | | | | | | | | | | | | | | In many cases, pointers to memory are passed around, and these pointers refer to U-Boot memory, not host memory. This in itself is not a problem. However, in a few places, we cast that pointer back to a ulong (being a U-Boot memory address). It is possible to convert many of these cases to avoid this. However there are data structures (e.g. struct bootm_headers) which use pointers. We could with a lot of effort adjust the structs and all code that uses them to use ulong instead of pointers. This seems like an unacceptable cost, since our objective with sandbox is to minimise the impact on U-Boot code while maximising the features available to sandbox. Therefore, create a map_to_sysmem() function which converts from a pointer to a U-Boot address. This can be used sparingly when needed. Signed-off-by: Simon Glass <sjg@chromium.org>
