From: Haibo Chen Date: Wed, 12 Nov 2025 11:05:12 +0000 (+0800) Subject: mtd: spi-nor: micron-st: add mt35xu01gbba support X-Git-Url: https://gentwo.org/gitweb/?a=commitdiff_plain;h=a5dff51e190c20226cc5a6ade9a35fd71b22f42c;p=linux%2F.git mtd: spi-nor: micron-st: add mt35xu01gbba support mt35xu01gbba is similar with mt35xu512aba, but with two dies. mt35xu01gbba has SFDP and support 8D-8D-8D mode, but SFDP lack SNOR_F_IO_MODE_EN_VOLATILE, so add this fixup flags here. Besides, mt35xu01gbba do not support chip erase, but support die erase, so add that in late_init().
