| * | post/i2c: Add ability to ignore I2C devicesPeter Tyser2010-10-222-2/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to not report an I2C POST error for a set of given I2C addresses on bootup. This is useful for cases when a device may or may not be present, and neither case is considered an error. For example: - Some form factors such as XMC and Compact PCI Express have an I2C EEPROM whose address changes based on geographical address. Eg installed in one slot its EEPROM address is, 0x50, in another its 0x51, etc. This allows multiple devices to have their EEPROMs present on the same I2C bus. Thus the I2C devices present for an XMC or CPCIe card depend on if and where other cards are installed in the same system. - Some cards have optional I2C devices. Eg one hardware build configuration has different I2C devices than another and software can't determine if the optional device should be present or not. - Some cards have optional daughtercards with I2C devices on them. - I2C EEPROMs address range depends on their size. Its possible to support differently size EEPROMs by only probing the EEPROM's base address and ignoring the other addresses that are impacted by its size. A new CONFIG_SYS_POST_I2C_IGNORES define has been added which specifies a list of I2C addresses for the I2C POST to ignore.

| * | post/i2c: Don't probe address 0Peter Tyser2010-10-221-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the I2C specification device address 0 is the "general call address", ie a broadcast address. The I2C specification states that the format of a general call uses at least 2 bytes, which U-Boot's probing routine does not adhere to. Not probing device address 0 will prevent possible issues with devices that accept general calls. Additionally, this change shouldn't reduce POST coverage since each I2C device should still be accessed via its own, unique address.

| * | xes: Make X-ES board names more genericPeter Tyser2010-10-2220-19/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some U-Boot images for X-ES boards support multiple products in the same family. For example, the XPedite5370, XPedite5371, and XPedite5372 are similar enough that one U-Boot image can work on all 3 cards. To make it clear that a U-Boot image can work on boards of the same family, rename the boards with the least significant digit of 'x'. While we're at it, change the board config file and make targets to be lowercase. Also change the default uImage and fdt filenames to "board.uImage" and "board.dtb" to be more generic.

It falls into class of typical USB problems and fixes: if you don't understand the real cause, add a delay somewhere. The problem appeared after introduction of ELF relocation, which results in smaller code, which appears to run faster (probably because it fits better in the cache); turning off the instruction cache, adding debug printf()s and increasing the delay have all been found to make the problem go away. Moving the original "udelay(1)" up in the code to it's new place made the problem appear much less frequently. Increasing the delay to 2 microseconds then made the code run reliably in all (hour-long) tests. To be on the safe side, we set it to 5 microseconds here.

When we install bigger chip (say 64MB) on such a board strange things happen (flash_write() doesn't work at all, for ex). That's because cfi_flash driver doesn't care about window size at all. Of course, cleanest solution would probably be to just extend address window to be able to map the whole flash but for legacy/compatibility reasons some people prefer just truncate the flash size and never use the upper part. This patch adds an option for cfi_flash driver to handle this situation properly. To achieve this we add the new function cfi_flash_bank_size() which can be provided by the board code and weak-aliased to default implementation that returns value from the CONFIG_SYS_FLASH_BANKS_SIZES array if it's defined or 0 otherwise (the last case is added for compatibility). If non-zero flash bank size is provided and detected chip size is bigger than provided address window size the warning will be displayed and flash chip will be truncated.
