Subject: [PATCH v1 0/5] Add SPI Driver to HPE GXP Architecture
Date: Wed, 20 Jul 2022 15:11:53 -0500 [thread overview]
Message-ID: <20220720201158.78068-1-nick.hawkins@hpe.com> (raw)
From: Nick Hawkins <nick.hawkins@hpe.com>
The GXP supports 3 separate SPI interfaces to accommodate the system
flash, core flash, and other functions. The SPI engine supports variable
clock frequency, selectable 3-byte or 4-byte addressing and a
configurable x1, x2, and x4 command/address/data modes. The memory
buffer for reading and writing ranges between 256 bytes and 8KB. This
driver supports access to the core flash and bios part.
