* fsl: verify writes to the MAC address EEPROMTimur Tabi2010-10-07-1/+17
| | | | | | | | | | | | Update the code which writes to the on-board EEPROM so that it can detect if the write failed because the EEPROM is write-protected. Most of the 8xxx-class Freescale reference boards use an AT24C02 EEPROM to store MAC addresses and similar information. With this patch, if the EEPROM is protected, the "mac save" command will display an error message indicating that the write has not succeeded.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* p2020ds: add alternate boot bank support using the ngPIXIS FPGATimur Tabi2010-04-07-0/+194
| | | | | | | | | | | | | | | The Freescale P2020DS board uses a new type of PIXIS FPGA, called the ngPIXIS. The ngPIXIS has one distinct new feature: the values of the on-board switches can be selectively overridden with shadow registers. This feature is used to boot from a different NOR flash bank, instead of having a register dedicated for this purpose. Because the ngPIXIS is so different from the previous PIXIS, a new file is introduced: ngpixis.c. Also update the P2020DS checkboard() function to use the new macros defined in the header file.

* fsl: improve the PIXIS code and fix a few bugsTimur Tabi2010-04-07-159/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx boards. This makes the code easier to read and more flexible. Delete pixis.h, because none of the exported functions were actually being used by any other file. Make all of the functions in pixis.c 'static'. Remove "#include pixis.h" from every file that has it. Remove some unnecessary #includes. Make 'pixis_base' into a macro, so that we don't need to define it in every function. Add "while(1);" loops at the end of functions that reset the board, so that execution doesn't continue while the reset is in progress. Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where appropriate. Replace ulong/uint with their spelled-out equivalents. Remove unnecessary typecasts, changing the types of some variables if necessary. Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make it easier for specific boards to support variations in the PIXIS registers sets. No current boards appears to need this feature. Fix the definition of CONFIG_SYS_PIXIS_VBOOT_MASK for the MPC8610 HPCD. Apparently, "pixis_reset altbank" has never worked on this board.

* fsl: simplify the "mac id" command, improve boot-time informational messageTimur Tabi2009-08-28-32/+49
| | | | | | | | | | | | | | | | | | | | | | | | | The "mac id" command took a 4-character parameter as the identifier string. However, for any given board, only one kind of identifier is acceptable, so it makes no sense to ask the user to type it in. Instead, if the user enters "mac id", the identifier (and also the version, if it's NXID) will automatically be set to the correct value. Improve the message that is displayed when EEPROM is read during boot. It now displays "EEPROM:" and then either an error message or the EEPROM identifier if successful. If the identifier in EEPROM is valid, then always reject a bad CRC, even if the CRC field has not been initialized. Don't force the MAC address count to MAX_NUM_PORTS or less. Forcing the value to be changed resulting in an in-memory copy that does not match what's in hardware, even though the user did not request that change. Finally, always update the CRC value in the in-memory copy after any field is changed, so that the CRC is always correct.

* fsl_diu: fix alignment error that caused malloc corruptionNikita V. Youshchenko2008-10-14-3/+3
| | | | | | | | | | | | | | | | | | | When aligning malloc()ed screen_base, invalid offset was added. This not only caused misaligned result (which did not cause hardware misbehaviour), but - worse - caused screen_base + smem_len to be out of malloc()ed space, which in turn caused breakage of futher malloc()/free() operation. This patch fixes screen_base alignment. Also this patch makes memset() that cleans framebuffer to be executed on first initialization of diu, not only on re-initialization. It looks correct to clean the framebuffer instead of displaying random garbage; I believe that was disabled only because that memset caused breakage of malloc/free described above - which no longer happens with the fix described above.

* Add pixis_set_sgmii commandAndy Fleming2008-09-02-0/+55
| | | | | | | | | | | | | | | | | | The 8544DS and 8572DS platforms support an optional SGMII riser card to expose ethernet over an SGMII interface. Once the card is in, it is also necessary to configure the board such that it uses the card, rather than the on-board ethernet ports. This can either be done by flipping dip switches on the motherboard, or by modifying registers in the pixis. Either way requires a reboot. This adds a command to allow users to choose which ports are routed through the SGMII card, and which through the onboard ports. It also allows users to revert to the current switch settings. This code does not work on the 8572, as the PIXIS is different. Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
