2013-10-08exynos: Export timer_get_us() to get microsecond timerRajeshwari Shinde
This function, if implemented by the board, provides a microsecond timer. The granularity may be larger than 1us if hardware does not support this.

2013-10-07Fix number base handling of "load" commandWolfgang Denk
As documented, almost all U-Boot commands expect numbers to be entered in hexadecimal input format. (Exception: for historical reasons, the "sleep" command takes its argument in decimal input format.) This rule was broken for the "load" command; for details please see especially commits 045fa1e "fs: add filesystem switch libary, implement ls and fsload commands" and 3f83c87 "fs: fix number base behaviour change in fatload/ext*load". In the result, the load command would always require an explicit "0x" prefix for regular (i. e. base 16 formatted) input. Change this to use the standard notation of base 16 input format. While strictly speaking this is a change of the user interface, we hope that it will not cause trouble. Stephen Warren comments (see [1]): I suppose you can change the behaviour if you want; anyone writing "0x..." for their values presumably won't be affected, and if people really do assume all values in U-Boot are in hex, presumably nobody currently relies upon using non-prefixed values with the generic load command, since it doesn't work like that right now.

2013-10-07sf: Add memory mapped read supportPoddar, Sourav
Qspi controller can have a memory mapped port which can be used for data read. Added support to enable memory mapped port read. This patch enables the following: - It enables exchange of memory map address between mtd and qspi through the introduction of "memory_map" flag. - Add support to communicate to the driver that memory mapped transfer is to be started through introduction of new flags like "SPI_XFER_MEM_MAP" and "SPI_XFER_MEM_MAP_END". This will enable the spi controller to do memory mapped configurations if required.

According to the below formulae, f dpll = f ref * 2 * m /(n + 1) clockoutx2_Hmn = f dpll / (hmn+ 1) fref = 20 Mhz, m = 96, n = 4 gives f dpll = 768 Mhz For clockoutx2_Hmn to be 768, hmn + 1 should be 4.
