Subject: Hexagon: Add delay functions
X-Git-Tag: next-20110914~91^2~28
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8beb4df590aafea523d289a1a73e9a957c2740f0;p=karo-tx-linux.git

Hexagon: Add delay functions

Added read_current_timer elsewhere.

udelay is based off of __vmgettime() which returns processor ticks.

Removed __delay and CONFIG_GENERIC_CALIBRATE_DELAY.
