[U-Boot] RFC [PATCH 4/5 v5 RESEND] dreamplug: initial board support.
Jason Cooper
u-boot at lakedaemon.net
Fri Jul 29 17:17:04 CEST 2011
Copied wholeheartedly from board/Marvell/guruplug and modified to add support
for SPI NOR flash.
Also, the following features are used:
- Use the Marvell Integrated RTC.
- display Marvell CPU/L2/etc speeds if requested.
Note: this still uses MACH_TYPE_GURUPLUG until MACH_TYPE_DREAMPLUG is accepted
into mainline Linux. The source from Globalscale did the same.
Signed-off-by: Jason Cooper <u-boot at lakedaemon.net>
---
Changes from v1 to v2:
- resorted series to move 'make all' support last.
Changes from v2 to v3:
- Use MACH_TYPE_GURUPLUG for now until dreamplug support is in
Linux.
- Update MAINTAINERS.
- Collapse into one patch.
Changes from v3 to v4:
- update copyright info as recommended by Prafulla Wadaskar.
- maintain proper order in boards.cfg, MAINTAINERS, etc.
- label MPP's
- change back to MACH_TYPE_DREAMPLUG. This patch is just RFC
until the Dreamplug is supported in Linux (and MACH_TYPE_
added).
Changes from v4 to v5:
- Complete rewrite due to receiving u-boot source indirectly
from Global Scale Tech.
- Added driver for integrated RTC. (thx GST!)
- Added support for displaying CPU frequencies at boot. (thx
GST!)
- Adjust USB timeout to handle dreamplug EHCI chipset.
- Cleaned up MPP registers based on Global Scale code. (thx
GST!)
- broke out MACH_TYPE_DREAMPLUG changes since it's going to be a
while until the Linux arm tree gets sorted and accepts new
boards again. Since all Dreamplugs currently on the market
set r1 to MACH_TYPE_GURUPLUG, this allows the board to be
added to u-boot while waiting for Linux mainline. Once it's
in Linux mainline, then the last patch can be integrated to
use MACH_TYPE_DREAMPLUG.
Changes for v5 resend:
- include this changelog.
