[U-Boot] [U-Boot PATCH v2 00/10] Enable edma support for ti-qspi

[Vignesh R]

This patch series enables DMA for QSPI on dra7xx and am43xx.
Patch 1 and 2 make sure the buffers are mem aligned for dma operation.
Patch 3-6 add support for enabling and disabling of edma3 clocks on
am43xx and dra7xx. Patch 7-9 add dma functionality to ti_qspi driver.
Patch 10 enable edma3 support in dra7xx config files.

Tested on DRA74 EVM: http://pastebin.ubuntu.com/11813977/

changes in v2:
* Move edma related code to edma driver instead of handling it in
  ti-qspi driver.
