* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * MXC: Fix byte-ordering in SPI driver for i.MX31/i.MX51Stefano Babic2010-09-30-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The actual SPI driver for i.MX31 and i.MX51 controller use a wrong byte ordering, because it is supposed to work only with Freescale's devices, as the Power Controllers (PMIC). The driver is not suitable for general purposes, because the buffers passed to spi_xfer must be 32-bit aligned, as it is used mainly to send integer to PMIC devices. The patch drops any kind of limitation and makes the driver useful with devices controlled sending commands composed by single bytes (or by a odd number of bytes), such as spi flash, sensor, etc. Because the byte ordering is changed, any current driver using this controller must be adapted, too.

* | led_display: split led display support into generic and hw-dependent partsIlya Yanok2010-10-12-0/+58
|/ | | | | | | | | | | Split the display command into generic interface and hardware-specific realization for PDSP188x LED display found on hmi1001 and manroland boards. Simple interface for LED displays is defined in include/led-display.h and described in doc/README.LED_display. Driver-specific implementation was moved into drivers/misc/pdsp188x.c file (enabled with CONFIG_PDSP188x set). Signed-off-by: Ilya Yanok <yanok@emcraft.com>
* cmd_usage(): simplify return code handlingWolfgang Denk2010-07-24-20/+13
| | | | | | | | | | | | | | | | Lots of code use this construct: cmd_usage(cmdtp); return 1; Change cmd_usage() let it return 1 - then we can replace all these ocurrances by return cmd_usage(cmdtp); This fixes a few places with incorrect return code handling, too.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* ppc/p4080: Add support for CoreNet style platform LAWsKumar Gala2009-09-24-11/+115
| | | | | | | | | | | | | | | | On CoreNet based platforms the LAW address is split between an high & low register and we no longer shift the address. Also, the target IDs on CoreNet platforms have been completely re-assigned. Additionally, added a new find_law() API to which LAW an address hits in. This is need for the CoreNet style boot release code since it will need to determine what the target ID should be set to for boot window translation. Finally, enamed LAWAR_EN to LAW_EN and moved to header so we can use it elsewhere. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* ppc/85xx: add boot from NAND/eSDHC/eSPI supportMingkai Hu2009-09-15-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MPC8536E is capable of booting form NAND/eSDHC/eSPI, this patch implements these three bootup methods in a unified way - all of these use the general cpu/mpc85xx/start.S, and load the main image to L2SRAM which lets us use the SPD to initialize the SDRAM. For all three bootup methods, the bootup process can be divided into two stages: the first stage will initialize the corresponding controller, configure the L2SRAM, then copy the second stage image to L2SRAM and jump to it. The second stage image is just like the general U-Boot image to configure all the hardware and boot up to U-Boot command line. When boot from NAND, the eLBC controller will first load the first stage image to internal 4K RAM buffer because it's also stored on the NAND flash. The first stage image, also call 4K NAND loader, will initialize the L2SRAM, load the second stage image to L2SRAM and jump to it. The 4K NAND loader's code comes from the corresponding nand_spl directory, along with the code twisted by CONFIG_NAND_SPL. When boot from eSDHC/eSPI, there's no such a first stage image because the CPU ROM code does the same work. It will initialize the L2SRAM according to the config addr/word pairs on the fixed address and initialize the eSDHC/eSPI controller, then load the second stage image to L2SRAM and jump to it. The macro CONFIG_SYS_RAMBOOT is used to control the code to produce the second stage image for all different bootup methods. It's set in the board config file when one of the bootup methods above is selected. Signed-off-by: Mingkai Hu <Mingkai.hu@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* OMAP3 Move twl4030 power and led functionsTom Rix2009-07-29-0/+53
| | | | | | | | | | | | | | | | | | | | | | | | Because twl4030 now has its own device files, move exiting omap3 power_init_r to a new location. power_init_r is the only function in board/omap3/common. It initializes the twl4030 power for the board and enables the led. The power part of the the function is moved to twl4030_power_init in drivers/power/twl4030.c The power compilation is conditional on the existing config variable CONFIG_TWL4030_POWER. The led part is moved to twl4030_led_init in the new file drivers/misc/twl4030_led.c The led compilation is conditional on the new config variable CONFIG_TWL4030_LED The directory board/omap3/common was removed because power_init_r was the only function in it.

* General help message cleanupWolfgang Denk2009-06-12-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
