2010-10-26Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

2010-10-18FDT: only call boot_get_fdt from generic codeJohn Rigby
All arches except nios2 and microblaze call boot_get_fdt from bootm_start in common/cmd_bootm.c. Having nios2 and microblaze do so as well removes code from their respective do_bootm_linux routines and allows removal of a nasty ifdef from bootm_start. In the case where boot_get_fdt returns an error bootm_start returns and the platform specific do_bootm_linux routines will never get called. Also only check argv[3] for an fdt addr if argc > 3 first. This is already the case for nios2.

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.

2010-07-04Make 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) { ...

2010-04-16microblaze: Consolidate cache codeMichal Simek
Merge cpu and lib cache code. Flush cache before disabling. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-16microblaze: Flush cache before jumping to kernelMichal Simek
There is used max cache size on system which doesn't define cache size. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-16microblaze: Support system with WB cacheMichal Simek
WB cache use different instruction that WT cache but the major code is that same. That means that wdc.flush on system with WT cache do the same thing as before. You need newer toolchain with wdc.flush support. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-16microblaze: Change initialization sequenceMichal Simek
env_relocation should be called first. Added stdio_init too. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-16microblaze: Change cache report messagesMichal Simek
It is more accurate to show that caches are OFF instead of FAIL. Signed-off-by: Michal Simek <monstr@monstr.eu>

Move FSL out of interrupt controller. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-16microblaze: Move timer initialization to board.cMichal Simek
I would like to handle case where system doesn't contain intc that's why I need timer initialization out of intc code. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-16microblaze: Add FDT supportArun Bhanu
This patch adds FDT (flattened device tree) support to microblaze arch. Tested with Linux arch/microblaze kernels with and without compiled in FDT on Xilinx ML506 board. Signed-off-by: Arun Bhanu <arun@bhanu.net> Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-04-13Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser
Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
