Subject: arm: vexpress64: Fix counter frequency
X-Git-Tag: baikal/mips/sdk5.9~316^2~6
X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=25f129d8c8ac94c8b2a196eb5de00070f642b208;p=uboot.git

arm: vexpress64: Fix counter frequency

The arch timer on 64-bit Arm Ltd. platforms is driven by a 24 MHz
crystal oscillator, so the frequency is not 25165824 MHz, as the current
code suggests.
