* Blackfin: bf537-stamp: use common spi boot workaround codeMike Frysinger2010-07-05-5/+2
| | | | | | | | The common gpio code provides a function for handling the spi boot workaround logic, so switch over to that rather than bang on the gpio MMRs directly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: unify custom gpio commandsMike Frysinger2010-07-05-202/+1
| | | | | | | Now that we have a unified gpio layer, the misc partial gpio commands can be unified and made complete (support all possible gpios). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf537-stamp: drop old spi_flash driverMike Frysinger2010-07-05-997/+0
| | | | | | | | The new common spi framework and spi flash subsystem provides all the same functionality as the old Blackfin-specific driver, so punt the old one as it has been sticking around long enough. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

* Replace "#include <asm-$ARCH/$FILE>" with "#include <asm/$FILE>"Peter Tyser2010-04-13-1/+1
| | | | | | | | | | The appropriate include/asm-$ARCH directory should already by symlinked to include/asm so using the whole "asm-$ARCH" path is unnecessary. This change should also allow us to move the include/asm-$ARCH directories into their appropriate lib/$ARCH/ directories. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Rename lib_generic/ to lib/Peter Tyser2010-04-13-2/+2
| | | | | | | | Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Change directory-specific CFLAGS to use full pathPeter Tyser2010-04-13-1/+1
| | | | | | | | | | | | | | | | | | Previously, a specific file or directory could be compiled with custom CFLAGS by adding a Makefile variable such as: CFLAGS_dlmalloc.o = <custom flags for common/dlmalloc.c> or CFLAGS_lib = <custom flags for lib directory> This method breaks down once multiple files or directories share the same path. Eg FLAGS_fileA = <custom flags> would incorrectly result in both dir1/fileA.c and dir2/fileA.c being compiled with <custom flags>. This change allows finer grained control which we need once we move lib_$ARCH to arch/$ARCH/lib/ and lib_generic/ to lib/. Without this change all lib/ directories would share the same custom CFLAGS.

* 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>

* 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

* 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>
