+Subject: [PATCH] arm: provide noncached_set_region prototype to fix build
+
+Due to the removal of weak functions in 7d6cee2cd0 ("cmd: cache: Remove
+weak function"), uboot fails to compile after updating to v2024.10 for
+mediatek target in OpenWrt with GCC-14 with error:
+cmd/cache.c: In function 'do_dcache':
+cmd/cache.c:57:25: error: implicit declaration of function
+ 'noncached_set_region' [-Wimplicit-function-declaration]
+
+Thus, provide a prototype in arm's include/asm/system.h to fix a build
+error in cmd/cache.c, since related prototypes are also located there.
+Also add an include of asm/system.h in cmd/cache.c have the function
+available there.
