2011-04-08Blackfin: move CONFIG_BFIN_CPU back to board config.hMike Frysinger
This is a revert of 821ad16fa9900c as Wolfgang doesn't like the new code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-04-08Blackfin: unify bootmode based LDR_FLAGS setupMike Frysinger
Unify this convention for all Blackfin boards. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-04-08Blackfin: drop CONFIG_SYS_TEXT_BASE from boardsMike Frysinger
We don't want/use this value for Blackfin boards, so punt it and have the common code error out when people try to use it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
2010-10-18Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk
The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

2010-10-02Blackfin: move CONFIG_BFIN_CPU to board config.mkMike Frysinger
The CONFIG_BFIN_CPU option is largely used in the build system, so move it out of the board config.h and into the board config.mk. It'd be nice to keep everything in the config.h, but the patch to extract that value early was rejected. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-02Blackfin: bf537-stamp: post: update old MMR style macrosMike Frysinger
The old MMR defines are being scrubbed, so convert the driver to use the new standard helper macros. For the GPIO MMR usage, convert to the new GPIO framework. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-07-05Blackfin: bf537-stamp: use common spi boot workaround codeMike Frysinger
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>
2010-07-05Blackfin: unify custom gpio commandsMike Frysinger
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>
2010-07-05Blackfin: bf537-stamp: drop old spi_flash driverMike Frysinger
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>
2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
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) { ...

2010-04-13Replace "#include <asm-$ARCH/$FILE>" with "#include <asm/$FILE>"Peter Tyser
The appropriate include/asm-$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/$ARCH/ directories. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2010-04-13Rename lib_generic/ to lib/Peter Tyser
Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2010-04-13Change directory-specific CFLAGS to use full pathPeter Tyser
Previously, a specific file or directory could be compiled with custom CFLAGS by adding a Makefile variable such as: CFLAGS_dlmalloc.o = <custom flags for common/dlmalloc.c> or CFLAGS_lib = <custom flags for lib directory> This method breaks down once multiple files or directories share the same path. Eg FLAGS_fileA = <custom flags> would incorrectly result in both dir1/fileA.c and dir2/fileA.c being compiled with <custom flags>. This change allows finer grained control which we need once we move lib_$ARCH to arch/$ARCH/lib/ and lib_generic/ to lib/. Without this change all lib/ directories would share the same custom CFLAGS.

2010-01-17Blackfin: kill off useless initdram() usageMike Frysinger
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>
2009-07-07mtd: nand: new base driver for memory mapped nand devicesMike Frysinger
The BF537-STAMP Blackfin board had a driver for working with NAND devices that are simply memory mapped.

2009-06-15Blackfin: enable -O2 in lib_generic/ for ADI/Bluetechnix boardsMike Frysinger
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>
2009-06-14Blackfin: unify u-boot linker scriptsMike Frysinger
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>
2009-06-12General help message cleanupWolfgang Denk
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>
