* Blackfin: kill off useless initdram() usageMike Frysinger2010-01-17-7/+0
| | | | | | | While the initdram() function makes sense on some arches, it doesn't for Blackfin systems as it's always implemented the same way. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* mtd: nand: new base driver for memory mapped nand devicesMike Frysinger2009-07-07-101/+0
| | | | | | | | | The BF537-STAMP Blackfin board had a driver for working with NAND devices that are simply memory mapped. Since there is nothing Blackfin specific about this, generalize the driver a bit so that everyone can leverage it.

* Blackfin: enable -O2 in lib_generic/ for ADI/Bluetechnix boardsMike Frysinger2009-06-15-0/+3
| | | | | | | Building the compression code in lib_generic/ with -O2 rather than -Os gives a nice speed boost without too much code size increase. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: unify u-boot linker scriptsMike Frysinger2009-06-14-150/+1
| | | | | | | | | | | All the Blackfin linker scripts were duplicated across the board dirs with no difference save from the semi-often used ENV_IS_EMBEDDED option. So unify all of them in the lib_blackfin/ dir and for the few boards that need to embedded the environment directly, add a LDS_BOARD_TEXT define for them to customize via their board config file. This is much simpler than forcing them to duplicate the rest of the linker script. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* General help message cleanupWolfgang Denk2009-06-12-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>

* Blackfin: set proper LDRFLAGS for parallel booting LDRsMike Frysinger2009-01-07-1/+4
| | | | | | | In order to boot an LDR out of parallel flash, the ldr utility needs a few flags to tell it to generate the right header. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-24/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot changed in the Linux MTD code, since it was last ported from Linux to U-Boot. This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial. The following drivers must be examined carefully and maybe rewritten to some degree: cpu/ppc4xx/ndfc.c cpu/arm926ejs/davinci/nand.c board/delta/nand.c board/zylonite/nand.c Signed-off-by: William Juul <william.juul@tandberg.com> Signed-off-by: Stig Olsen <stig.olsen@tandberg.com> Signed-off-by: Scott Wood <scottwood@freescale.com>

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-1/+1
| | | | | | | | | | | | | | | | | | | This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
* Blackfin: unify cpu and boot modesMike Frysinger2008-03-30-172/+111
| | | | | | | | All of the duplicated code for Blackfin processors and boot modes have been unified. After all, the core is the same for all processors, just the peripheral set differs (which gets handled in the drivers). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: BF537-stamp: cleanup spi flash driverMike Frysinger2008-03-30-517/+816

* net/Blackfin: move on-chip MAC driver into drivers/net/Mike Frysinger2008-03-25-621/+1
| | | | | | | | The Blackfin on-chip MAC driver was being managed in the BF537-STAMP board directory, but it is not board specific, so relocate it to the drivers dir so that other Blackfin ports can utilize it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: BF537-stamp: drop board-specific flash driver for CFIMike Frysinger2008-03-15-527/+1
| | | | | | | The parallel flash on the BF537-STAMP is CFI compliant, so there is no need for the board specific driver at all. Just use the common CFI driver. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
