+From fda4bd9bac78efd2f9d566c52956d297bc03e8d9 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] powerpc/83xx: Add support for MPC8377E-WLAN boards
+
+MPC8377E-WLAN are basically RDB boards except:
+
+- RAM extended to 512 MB;
+- NAND flash removed, NOR flash extended to 64 MB;
+- Vitesse VSC7385 5-port switch removed, RTL8211B PHY added;
+- Power management MCU removed;
+- PCI slot removed, another mini-PCI slot added (IRQ routing changed);
+- USB3300 PHY's ID pin grounded, thus USB port is host-only.

+Subject: [PATCH] powerpc: introduce and document sdhci,wp-inverted property for eSDHC
+
+eSDHC block in MPC837x SOCs reports inverted write-protect state, soon
+sdhci-of driver will look for sdhci,wp-inverted properties to decide
+whether apply a specific quirk.
+
+So, document the property and add it to device tree source files.
