+Subject: [PATCH] nvmem: add new NXP QorIQ eFuse driver
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add SFP (Security Fuse Processor) read support for NXP (Freescale)
+QorIQ series SOC's.
+
+This patch adds support for the T1023 SOC using the SFP offset from
+the existing T1023 device tree. In theory this should also work for
+T1024, T1014 and T1013 which uses the same SFP base offset.

+Subject: [PATCH] nvmem: sec-qfprom: Add Qualcomm secure QFPROM support
+
+For some of the Qualcomm SoC's, it is possible that
+some of the fuse regions or entire qfprom region is
+protected from non-secure access. In such situations,
+the OS will have to use secure calls to read the region.
+With that motivation, add secure qfprom driver.

+ DECLARE_FLEX_ARRAY() helper
+
+We are moving toward replacing zero-length arrays with C99 flexible-array
+members since they are deprecated. Therefore, the new DECLARE_FLEX_ARRAY()
+helper macro should be used to replace the zero-length array declaration.
+
+This fixes warnings such as:
+./drivers/nvmem/u-boot-env.c:50:9-13: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)

+Subject: [PATCH] nvmem: core: Return NULL when no nvmem layout is found
+
+Currently, of_nvmem_layout_get_container() returns NULL on error, or an
+error pointer if either CONFIG_NVMEM or CONFIG_OF is turned off. We
+should likely avoid this kind of mix for two reasons: to clarify the
+intend and anyway fix the !CONFIG_OF which will likely always if we use
+this helper somewhere else. Let's just return NULL when no layout is
+found, we don't need an error value here.
