2010-09-03avr32: Add simple paging supportHaavard Skinnemoen
Use the MMU hardware to set up 1:1 mappings between physical and virtual addresses. This allows us to bypass the cache when accessing the flash without having to do any physical-to-virtual address mapping in the CFI driver. The virtual memory mappings are defined at compile time through a sorted array of virtual memory range objects. When a TLB miss exception happens, the exception handler does a binary search through the array until it finds a matching entry and loads it into the TLB. The u-boot image itself is covered by a fixed TLB entry which is never replaced. This makes the 'saveenv' command work again on ATNGW100 and other boards using the CFI driver, hopefully without breaking any rules. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
2010-09-03avr32: Print unrelocated PC on exceptionHaavard Skinnemoen
In addition to the real PC value, also print the value of PC after subtracting the relocation offset. This value will match the address in the ELF file so it's much easier to figure out where things went wrong. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>

2010-08-11Blackfin: shutdown video DMA when booting LinuxMichael Hennerich
In case there is no frame buffer driver present in Linux to hand over the PPI LCD DMA upon boot, the DMA initiated by u-boot to display the splash screen runs unattended. Therefore always stop the video driver in u-boot before starting Linux. If people don't want this behavior, then they can simply stub out the video_stop() function in their board video driver.

2010-08-10orion5x: allow overriding default mappings windowsAlbert Aribaud
Turn all ORION5X_DEF{ADR,SZ}_xxx macros into ORION5X_{ADR,SZ}_xxx and allow defining them from board code to override defaults. This is particularly useful for defining board-specific FLASH address and size in board header file rather than having to tweak orion5x code. Signed-off-by: Albert Aribaud <albert.aribaud@free.fr>

2010-08-08fdt relocate: have more attention to use a bootmap or notStephan Linz
Platforms with flat device tree support can use a bootmap to relocate the fdt_blob. This is not a must. That's why the relocation function boot_relocate_fdt() should be use only if CONFIG_OF_LIBFDT was defined together with CONFIG_SYS_BOOTMAPSZ (see common/cmd_bootm.c). On MicroBlaze platforms there is no need to use a bootmap to relocate a fdt blob. So we need a more precise focus on the compilation and usage of boot_relocate_fdt(). In general it is valid to exclude the function boot_relocate_fdt() if the bootmap size CONFIG_SYS_BOOTMAPSZ is not defined. Signed-off-by: Stephan Linz <linz@li-pro.net>

2010-08-03Rename getenv_r() into getenv_f()Wolfgang Denk
While running from flash, i. e. before relocation, we have only a limited C runtime environment without writable data segment. In this phase, some configurations (for example with environment in EEPROM) must not use the normal getenv(), but a special function. This function had been called getenv_r(), with the idea that the "_r" suffix would mean the same as in the _r_eentrant versions of some of the C library functions (for example getdate vs. getdate_r, getgrent vs. getgrent_r, etc.). Unfortunately this was a misleading name, as in U-Boot the "_r" generally means "running from RAM", i. e. _after_ relocation. To avoid confusion, rename into getenv_f() [as "running from flash"] Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>

2010-07-25Blackfin: jtag-console: handle newline stuffingMike Frysinger
Serial devices currently have to manually stuff \r after every \n found, but this is a bit more difficult with the jtag console since we process everything in chunks of 4 bit. So we have to scan & stuff the whole string rather than what most serial drivers do which is output on a byte per byte basis. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-07-25Blackfin: jtag-console: add debug markersMike Frysinger
While we're in here, add some useful debug points. We need custom debug statements because we need the output to only go to the serial port. If we used the standard debug helpers, the output would also go to the stdout (which would be the jtag console) and make it hard to figure out what is going where exactly.

2010-07-25Blackfin: jtag-console: robustify against missing peerMike Frysinger
