* MX28: Fix MXS MMC DMA issuesMarek Vasut2012-09-01-15/+19
| | | | | | | | | | | | The DMA didn't work properly because the DMA descriptor wasn't properly cleaned after it was used once. Also, the DMA_ENABLE bit was enabled/disabled too late.

* MX28: SPI: Add DMA transfer supportMarek Vasut2012-09-01-1/+116
| | | | | | | | | | | | | | | | | The DMA transfers happen only if the transfered data are larger than 512 bytes. Otherwise PIO is used. This is a small speed optimization. The DMA transfer doesn't work if unaligned transfer is requested due to the limitation of the DMA controller. This has to be fixed by introducing generic bounce buffer. Therefore the DMA feature is now disabled by default.

* DaVinci DA8xx: fix set_cpu_clk_info()Laurence Withers2012-09-01-9/+14
| | | | | | | | | | | | | | | | | | | | | | For the DA8xx family of SoCs, the set_cpu_clk_info() function was not initialising the DSP frequency, leading to 'bdinfo' command output such as: [...snip...] ARM frequency = 300 MHz DSP frequency = -536870913 MHz DDR frequency = 300 MHz This commit provides a separate implementation of set_cpu_clk_info() for the DA8xx SoCs that initialises the DSP frequency to zero (since currently the DSP is not enabled by U-Boot on any DA8xx platform). The separate implementation is justified because there is no common code between DA8xx and the other SoC families. It is now much easier to understand the flow of the two separate functions.

| | | | | | | | | | On the DA830, UART2's clock is derived from PLL controller 0 output 2. On the DA850, it is in the ASYNC3 group, and may be switched between PLL controller 0 or 1.

| | | | | | | | | | | | | | The ddr_regs struct was incorrectly offset after the dt0wiratio0 entry. Correct this by documenting a missing register that will be used at some point in the future (when write leveling is supported). Further, the cmdNcs{force,delay} fields are undocumented and we have been setting them to zero, remove. Next, setting of the 'DATAn_REG_PHY_USE_RANK0_DELAYS field belongs with the rest of the ddr_data entries, so program it there.
