Subject: Re: [PATCH 1/1] EmbeddedPkg: Implement NorFlashLib
Date: Wed, 1 Nov 2017 05:57:05 +0000 [thread overview]
Message-ID: <AM0PR0402MB39401EEF874A7F05AAC086FDF15F0@AM0PR0402MB3940.eurprd04.prod.outlook.com> (raw)
In-Reply-To: <CAPv3WKcdm482+cvfQA9pPU5MWnBuq2WBSBH3tw4oeKp9WtTiKg@mail.gmail.com>
Hi Marcin,
The SPI flash Jedec id is not standardized across flashes.
The JEDEDC group only assigns first byte (Manufacturer ID) to different vendors.
Rest of the bytes are up to the Manufacturer to decide.
Therefore this info should be left to the SPI flash driver to parse.
It should not be stored in tabular form rather calculated based on JEDEDC data read.
Thanks & Regards,
Pankaj Bansal
