[U-Boot] [PATCH v2 13/22] omap4: add clock support

Aneesh V
2011-05-15T15:21:31Z

Add support for:
1. DPLL locking
2. Initialization of clock domains and clock modules

This work draws upon previous work done for x-loader mainly by:
Santosh Shilimkar <santosh.shilimkar@ti.com>
Rajendra Nayak <rnayak@ti.com>

Signed-off-by: Aneesh V <aneesh@ti.com>
---
V2:
* Use pre-calculated M & N values instead of calculated ones
* Changes due to make file changes
* Some corrections
* Do all clock initialization in SPL itself instead of differing some
work to u-boot
