* 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) { ...

| | | | | | | | | | The "-ffixed-r15" option doesn't work well for gcc4. Since we don't use gp for small data with option "-G0", we can use gp as global data pointer. This allows compiler to use r15.

| | | | | | | | | | | | | | | | Add a new function to the eth_device struct for programming a network controller's hardware address. After all network devices have been initialized and the proper MAC address for each has been determined, make a device driver call to program the address into the device.

* Move arch/ppc to arch/powerpcStefan Roese2010-04-21-49/+49
| | | | | | | | | | | | | | | | | As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.

| | | | | | | | | | | | The CPUDIR variable points to the location of a target's CPU directory. Currently, it is set to cpu/$CPU. However, using $CPUDIR will allow for more flexibility in the future.

* 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>

* sbc8548: reclaim wasted sector in boot flashPaul Gortmaker2009-09-30-0/+24
| | | | | | | | | | | | | | | | | | | | | | | By nature of being based off the MPC8548CDS board, this board inherited an ENV_SIZE setting of 256k. But since it has a smaller flash device (8MB soldered on), it has a native sector size of 128k, and hence the ENV_SIZE was causing 2 sectors to be used for the environment. By removing the unused sector, we can push TEXT_BASE up closer to the end of address space and reclaim that sector for any other application. This also fixes the mismatch between TEXT_BASE and MONITOR_LEN reported by Kumar earlier. Since this board also supports the ability to boot off the 64MB SODIMM flash, this change is forward looking with that in mind; i.e. the settings for MONITOR_LEN and ENV_SIZE will work when the 512k sectors of the SODIMM flash are used for alternate boot in the future.

This moves the TEXT_BASE to be the beginning of flash, which makes the second copy of the image redundant, and frees up the flash from the end of the environment storage to the end of the flash device itself.
