+Subject: [PATCH] Qemu:Arm:versatilepb: Add memory size checking
+
+The machine can not work with memory over 256M, so add a checking
+at startup. If the memory size exceed 256M, just stop emulation then
+throw out warning about memory limitation.

+qemu: Add addition environment space to boot loader qemu-system-mips 
+
+Upstream-Status: Inappropriate - OE uses deep paths
+
+If you create a project with very long directory names like 128 characters
+deep and use NFS, the kernel arguments will be truncated. The kernel will
+accept longer strings such as 1024 bytes, but the qemu boot loader defaulted
+to only 256 bytes. This patch expands the limit.
