* ARMV7: OMAP: I2C driver: Restructure i2c_read_byte functionSteve Sakoman2010-10-20-39/+37
| | | | | | | | This patch removes the "magic number" delays and instead monitors state changes in the status register bits. Signed-off-by: Steve Sakoman <steve.sakomanlinaro.org> Tested-by: Heiko Schocher <hs@denx.de>
* ARMV7: OMAP: I2C driver: Use same timeout value as linux kernel driverSteve Sakoman2010-10-20-6/+8
| | | | | | | | | | This patch matches the poll interval (1 millisecond) and timeout (1 second) used in the linux driver. It also adds a return value of 0 in the event of a timeout error and cleans up some formatting errors in that section of the code.

* FAT: buffer overflow with FAT12/16Stefano Babic2010-10-20-1/+1
| | | | | | | | | | | | | Last commit 3831530dcb7b71329c272ccd6181f8038b6a6dd0a was intended "explicitly specify FAT12/16 root directory parsing buffer size, instead of relying on cluster size". Howver, the underlying function requires the size of the buffer in blocks, not in bytes, and instead of passing a double sector size a request for 1024 blocks is sent. This generates a buffer overflow with overwriting of other structure (in the case seen, USB structures were overwritten).

* USB: sync Queue Element Transfer Descriptor against EHCI specWolfgang Denk2010-10-20-5/+10
| | | | | | | | | | | | | | | | | | | Appendix B "EHCI 64-Bit Data Structures" of the "Enhanced Host Controller Interface Specification for Universal Serial Bus" (Rev. 1.0, March 12, 2002) defines additional fields which were missing in U-Boot's struct qTD; as these are also present in recent versions of struct ehci_qtd in the Linux kernel, we add them here, too. This fixes some nasty memory corruption problems.

| * PXA: Fix reloc, Push lowlevel init into C codeMarek Vasut2010-10-19-214/+359
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Firstly, this fixes relocation issues. I had to use part of Dcache as RAM for a while. I also moved around the lowlevel init code. It turned out so most of the lowlevel init code ended in cpu.c (and eventually was rewritten into C). This will also allow easier operation with FDT, multi-CPU-model support etc. in later releases. NOTE: This breaks most of the PXA boards (actually, the reloc stuff did already, this only finishes the doom). Signed-off-by: Marek Vasut <marek.vasut@gmail.com>

Later we use r6 to setup MDREFR[APD] bit. As result MDREFR[APD] is always zero. Signed-off-by: Mikhail Kshevetskiy <mikhail.kshevetskiy@gmail.com>
| * PXA: fix environment sector size, kernel and environment location for vpac270Mikhail Kshevetskiy2010-10-19-8/+17
| | | | | | | | | | | | | | | | | | | | Define ENV_ADDR as MONITOR_BASE + MONITOR_LEN. Fix environment sector size (NOR: 32Kb for first four sectors and 128Kb for other; OneNAND: 128Kb). Last but not least: we have MONITOR_LEN = 0x40000 and one sector for environment (size = 0x20000), so the kernel may start from 0x00060000 only.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes some functionality from at91rm9200ek board but the remaining functionality does now work with newer at91 code and arm-relocation. Currently missing features are: - dataflash booting (due to missing HW for testing) - MMC/SD-Card - first stage bootloader support is completely removed (not needed for NOR) Cause this board was (some days ago) reference for all at91rm9200 based boards this should be a good starting point to convert all remaining at91rm9200 borads to at91 code. Aside from that this is a good base to get some drivers between at91sam/at91rm/avr32 merged.
