Subject: [U-Boot] [PATCH v2 1/2] flash: add device ID for Microchip PIC32 internal flash.
Date: Tue, 15 Mar 2016 15:46:52 +0530	[thread overview]
Message-ID: <1458037013-8496-1-git-send-email-purna.mandal@microchip.com> (raw)

Microchip PIC32 has internal parallel flash (non-CFI compliant).
These flash devices do not support any identifier command so no
standard IDs. Added unique IDs to seperate these flash devices
from others supported by U-Boot.
