* Remove unused CONFIG_SERIAL_SOFTWARE_FIFO featureStefan Roese2010-09-23-6/+0
| | | | | | | | | This patch removes the completely unused CONFIG_SERIAL_SOFTWARE_FIFO feature from U-Boot. It has only been implemented for PPC4xx and was not used at all. So let's remove it and make the code smaller and cleaner. Signed-off-by: Stefan Roese <sr@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>
* ARM: implement relocation for ARM926Heiko Schocher2010-09-19-0/+23
| | | | | | | | | | | | | | | | | | | | | Change the implementation for arm926 to relocate the code to an arbitrary address in RAM. Adapt the TX25 (i.MX25), magnesium board to test the changes. On the tx25 board TEXT_BASE is set to the final relocation address to prevent one more copying of u-boot code when relocating.

* ARM: add relocation supportHeiko Schocher2010-09-19-0/+321
| | | | | | | | | | | | | | | | | | | !! This breaks support for all arm boards !! To compile in old style, you must define CONFIG_SYS_ARM_WITHOUT_RELOC or you can compile with "CONFIG_SYS_ARM_WITHOUT_RELOC=1 ./MAKEALL board" !! This define will be removed soon, so convert your board to use relocation support Portions of this work were supported by funding from the CE Linux Forum.

* 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) { ...

* Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an ↵Luigi 'Comio' Mantellini2009-10-10-0/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arbitrary number of mii buses. This feature is useful when your board uses different mii buses for different phys and all (or a part) of these buses are implemented via bit-banging mode. The driver requires that the following macros should be defined into the board configuration file: CONFIG_BITBANGMII - Enable the miiphybb driver CONFIG_BITBANGMII_MULTI - Enable the multi bus support If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs to define at least the following macros: MII_INIT - Generic code to enable the MII bus (optional) MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional) MDIO_ACTIVE - Activate the MDIO pin as out pin MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin MDIO_READ - Read the MDIO pin MDIO(v) - Write v on the MDIO pin MDC_DECLARE - Declaration needed to access to the MDC pin (optional) MDC(v) - Write v on the MDC pin The previous macros make the driver compatible with the previous version (that didn't support the multi-bus). When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill the bb_miiphy_buses[] array with a record for each required bus and declare the bb_miiphy_buses_num variable with the number of mii buses. The record (struct bb_miiphy_bus) has the following fields/callbacks (see miiphy.h for details): char name[] - The symbolic name that must be equal to the MII bus registered name int (*init)() - Initialization function called at startup time (just before the Ethernet initialization) int (*mdio_active)() - Activate the MDIO pin as output int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin int (*set_mdio)() - Write the MDIO pin int (*get_mdio)() - Read the MDIO pin int (*set_mdc)() - Write the MDC pin int (*delay)() - Delay function void *priv - Private data used by board specific code The board code will look like: struct bb_miiphy_bus bb_miiphy_buses[] = { { .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... }, { .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... }, ... int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) / sizeof(bb_miiphy_buses[0]); Signed-off-by: Luigi 'Comio' Mantellini <luigi.mantellini@idf-hit.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
