[U-Boot] [PATCH v6] arm: Add sata support on Layerscape ARMv8 board

From: Tang Yuantian Yuantian.Tang@freescale.com

Freescale ARM-based Layerscape contains a SATA controller which comply with the serial ATA 3.0 specification and the AHCI 1.3 specification. This patch adds SATA feature on ls2080aqds, ls2080ardb and ls1043aqds boards.

Signed-off-by: Tang Yuantian Yuantian.Tang@freescale.com --- v6: - update rx watermark from 0x25 to 0x29 to improve compatibility v5: - re-organize the code v4: - rebase to lastest git tree - add another ARMv8 platform which is ls1043aqds v3: - rename ls2085a to ls2080a - rebase to the latest git tree - replace the magic number with micro variable v2: - rebase to the latest git tree
