* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-36/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-0/+5
| | | | | | | | | | | | | | | | | | 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.

* Makefile: move all Power Architecture boards into boards.cfgWolfgang Denk2010-10-18-202/+25
| | | | | | | | | | Clean up Makefile, and drop a lot of the config.mk files on the way. We now also automatically pick all boards that are listed in boards.cfg (and with all configurations), so we can drop the redundant entries from MAKEALL to avoid building these twice.

* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-36/+36
| | | | | | | | | | | | 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.

| * ppc4xx: Use common NS16550 driver for PPC4xx UARTStefan Roese2010-09-23-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the PPC4xx UART driver. Instead the common NS16550 driver is used, since all PPC4xx SoC's use this peripheral device. The file 4xx_uart.c now only implements the UART clock calculation function which also sets the SoC internal UART divisors. All PPC4xx board config headers are changed to use this common NS16550 driver now. Tested on these boards: acadia, canyonlands, katmai, kilauea, sequoia, zeus Signed-off-by: Stefan Roese <sr@denx.de>
| * ppc4xx: Big header cleanup part 2, mostly PPC405 relatedStefan Roese2010-09-23-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This cleanup is done by creating header files for all SoC versions and moving the SoC specific defines into these special headers. This way the common header ppc405.h and ppc440.h can be cleaned up finally. As a part from this cleanup, the GPIO definitions for PPC405EP are corrected. The high and low parts of the registers (for example CONFIG_SYS_GPIO0_OSRL vs. CONFIG_SYS_GPIO0_OSRH) have been defined in the wrong order. This patch now fixes this issue by switching these xxxH and xxxL values. This brings the GPIO 405EP port in sync with all other PPC4xx ports. Signed-off-by: Stefan Roese <sr@denx.de>

* | ppc4xx/fdt/flash: Change fdt_fixup_nor_flash_node() to not rely on cs sizeStefan Roese2010-09-23-0/+31
|/ | | | | | | | | | | | | | | | | | | | | | This patch changes the behaviour of the fdt_fixup_nor_flash_node() function. Now it doesn't patch the size of the "reg" property with the chip-select size, but with the size returned from the new function flash_get_bank_size(). This function will return per weak default the flash size of the bank (bank = chip-select numer) detected by the flash driver. If this does not fit your needs, this function may be overridden by a board specific one. For this the parameters needed to be changed. So I intentionally squashed the PPC4xx stuff using this routine into this patch. Otherwise it would not be git-bisectable anymore. The board specific function for the AMCC/APM Ebony eval board is now included in this patch version.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-24/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

| | | | | | | | | | | | | | | | | | | | | | | | This patch adds new macros, with frequently used combinations of the 4xx TLB access control and storage attibutes. Additionally the 4xx init.S files are updated to make use of these new macros. Resulting in easier to read TLB definitions. Additionally some init.S files are updated to use the mmu header for the TLB defines, instead of defining their own macros. Signed-off-by: Stefan Roese <sr@denx.de>

Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure.

* POST: Remove duplicated post_hotkey_pressed() functionsStefan Roese2009-12-07-78/+0

The long-running tests won't be started on those boards. This default function was implemented in many board directories. By implementing this weak default we can remove all those duplicate versions. Boards with hotkey support, can override this weak default function by defining one in their board specific code. Signed-off-by: Stefan Roese <sr@denx.de>

Please note that the patches with the dynamic PCI sync clock configuration have to be applied, before this one should go in. This is because Sequoia has 2 different bootstrap EEPROMs, and the old bootstrap command configured different values depending on the detected PCI async clock (33 vs. 66MHz).
