* Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk2010-10-29-2/+2
| | | | | | | | | | | By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions. To make this more obvious, we make working relocation now the default case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

| * ARMV7: OMAP: I2C driver: Fix bug found in 37XX testingSteve Sakoman2010-10-25-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On OMAP36/37XX the standard on chip pullups are not sufficient to ensure proper i2c operation without external pullups or switching to high speed mode and enabling special on chip pullups. This is an issue for Beagle xM, which does not have external pullups on the expansion board i2c lines. The issue manifests itself as an AL (arbitration lost) error when probing for a non-existent device (i.e. on a Beagle xM with no expansion boards attached). This issue does not occur on expansion boards that include pullups or on Overo 37XX COM's since they include pull-ups. This patch fixes the issue by checking for the AL bit in the i2c_probe function.

This command is enabled via the CONFIG_CMD_PCI_ENUM define and can be useful in boards with FPGAs connected via PCI/PCIe, boards that support PCI hot-plugging, or during PCI debug.

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.

* | cfi_flash: handle 'chip size exceeds address window' situationIlya Yanok2010-10-23-5/+23
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | On some boards we have flash mapped high in the address space with considerably small window (say 0xFE000000 and 32MB). 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.

Without this patch this board resets in the commands with long outputs, like "printenv" or "fdt print".

The driver is not suitable for general purposes, because the buffers passed to spi_xfer must be 32-bit aligned, as it is used mainly to send integer to PMIC devices. The patch drops any kind of limitation and makes the driver useful with devices controlled sending commands composed by single bytes (or by a odd number of bytes), such as spi flash, sensor, etc. Because the byte ordering is changed, any current driver using this controller must be adapted, too.
