* mx28: fix i.MX28 spi driverMatthias Fuchs2012-02-12-3/+9
| | | | | | | | | | | | | | | The generic spi flash driver (drivers/mtd/spi/spi_flash.c) uses the spi low level driver's spi_xfer() function with len=0 to deassert the SPI flash' chip select. But the i.MX28 spi driver rejects this call due to len=0. This patch implements an exception for len=0 with the SPI_XFER_END flag set. This results in an extra read with the chip select being deasserted afterwards. There seems to be no way to deassert the signal by hand.

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

| * MXC: Fix byte-ordering in SPI driver for i.MX31/i.MX51Stefano Babic2010-09-30-38/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The actual SPI driver for i.MX31 and i.MX51 controller use a wrong byte ordering, because it is supposed to work only with Freescale's devices, as the Power Controllers (PMIC). 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.

| * MXC: Correct SPI_CPOL setting in SPI driverStefano Babic2010-09-30-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The handling of the SPI_CPOL bit inside the SPI driver was wrong. As reported by the manual, the meaning of the SSPOL inside the configuration register is the same as reported by SPI specification (0 if low in idle, 1 is high on idle). The driver inverts this logic. Because this patch sets the logic as specified, it is required to clear the CPOL bit in the configuration file to adapt to the correct logic.

| * Use common function to set GPIOs for MX3 and MX5Stefano Babic2010-09-29-8/+7
| | | | | | | | | | | | | | | | | | The patch adds support for setting gpios to the MX51 processor and change name to the corresponding functions for MX31. In this way, it is possible to get rid of nasty #ifdef switches related to the processor type. Signed-off-by: Stefano Babic <sbabic@denx.de>
* | Blackfin: bfin_spi: add optional DMA supportMike Frysinger2010-10-02-27/+128
|/ | | | | | | | This moves the last piece from the old spi_flash driver to the new SPI framework -- optional DMA RX support. This typically cuts speeds by ~40% at the cost of additional ~300 bytes. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bfin_spi: use same gpio cs define as LinuxMike Frysinger2010-09-21-2/+0
| | | | | | | | Linux uses an offset of 8 to switch from hardware cs to a gpio cs, so have u-boot use the same value. Also make sure it is public for boards to access. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
