* fsl: obsolete NXID v0 EEPROMs, automatically upgrade them to NXID v1Timur Tabi2011-04-04-10/+40
| | | | | | | | | | | | | | | | | | The NXID EEPROM format comes in two versions, v0 and v1. The only difference is in the number of MAC addresses that can be stored. NXID v0 supports eight addresses, and NXID v1 supports 23. Rather than allow a board to choose which version to support, NXID v0 is now considered deprecated. The EEPROM code is updated to support only NXID v1, but it can still read EEPROMs formatted with v0. In these cases, the EEPROM data is loaded and the CRC is verified, but the data is stored into a v1 data structure. If the EEPROM data is written back, it is written in v1 format. This allows existing v0-formatted EEPROMs to continue providing MAC addresses, but any changes to the data will force an upgrade to the v1 format, while retaining all data.

* fsl: update CRC after setting EEPROM identifierTimur Tabi2011-02-09-0/+1
| | | | | | | | | | The "mac id" command is used to initialize the EEPROM data to a specific format, but it was not updating the CRC. This didn't cause any real problems, because writing the data to the EEPROM will always update the CRC anyway, but it did result in a bogus CRC warning.

* fsl: add support for NXID v1 EEPROM formatTimur Tabi2010-10-07-9/+17
| | | | | | | | | | | | | | Freescale application note AN3638 describes an update to the NXID format, which stores MAC addresses and related data on an on-board EEPROM. The new version adds support for up to 23 MAC addresses, instead of just 8. Since the initial implementation of NXID had a "0" in the 'version' field, this new version is called "v1". Boards that are shipped with EEPROMs in the NXID v1 format should define CONFIG_SYS_I2C_EEPROM_NXID_1 instead of CONFIG_SYS_I2C_EEPROM_NXID.

* 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.

* cmd_usage(): simplify return code handlingWolfgang Denk2010-07-24-4/+2
| | | | | | | | | | | | | | | | 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 Denk2010-07-04-1/+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) { ...

* 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: Fix get_cpu_board_revision() return value.Rafal Czubak2008-10-08-1/+1
| | | | | | | | | | | | | get_cpu_board_revision() returned board revision based on information stored in global static struct eeprom. It should instead use one from local struct board_eeprom, to which the data is actually read from EEPROM. The bug led to system hang after printing L1 cache information on U-Boot startup. The problem was observed on MPC8555CDS system and possibly affects other Freescale MPC85xx boards using CFG_I2C_EEPROM_CCID. The change has been successfully tested on MPC8555CDS system.

* Update Freescale sys_eeprom.c to handle CCID formatsTimur Tabi2008-07-15-206/+392
| | | | | | | | | | | | | Update the sys_eeprom.c file to handle both NXID and CCID EEPROM formats. The NXID format replaces the older CCID format, but it's important to support both since most boards out there still use the CCID format. This change is in preparation for using one file to handle both formats. This will also unify EEPROM support for all Freescale 85xx and 86xx boards. Also update the 86xx board header files to use the standard CFG_I2C_EEPROM_ADDR instead of ID_EEPROM_ADDR. Signed-off-by: Timur Tabi <timur@freescale.com>
