Subject: [PATCH edk2-platforms 1/5] Silicon/NXP/LS1043A: Fix the Platform PLL calculation
Date: Tue,  2 Jun 2020 18:54:59 +0530	[thread overview]
Message-ID: <20200602132503.27154-2-pankaj.bansal@oss.nxp.com> (raw)
In-Reply-To: <20200602132503.27154-1-pankaj.bansal@oss.nxp.com>

From: Pankaj Bansal <pankaj.bansal@nxp.com>

for LS1043A SOC the DCFG registers are read in big endian format.
However current Platofmr PLL calculation is being done assuing the
little endian format.

Fix the Platform PLL calculation
