Hi Paul, I have some good news and some bad news. Good news is: I tested this series of patches on CU1000-Neo & CU1830-Neo, and it can boot normally and log in to debian normally. Bad news is: 1. Because we dropped arch/mips/jz4740/setup.c, so it did not return MACH_INGENIC_XXXX correctly, which caused the correction of the L2 cache probe in arch/mips/mm/sc-mips.c to fail, causing JZ4770/X1000 to detect the L2 cache capacity incorrect. 2. When I did some heavy work (compiled docker source code after logging in with ssh), the following message appeared: message1: [ 4694.290776] warn_alloc: 25 callbacks suppressed [ 4694.290791] containerd-shim: page allocation failure: order:4, mode:0x40cc0(GFP_KERNEL|__GFP_COMP), nodemask=(null) [ 4694.315266] CPU: 0 PID: 19817 Comm: containerd-shim Not tainted 5.8.0-00013-g192f2fd7b678 #15 [ 4694.317993] Stack : 80ae0000 80a50000 80860000 809b8fb0 809e4a30 850dfcb4 00000000 ffffffff [ 4694.320818] 80a50000 80a576c7 809c4374 00004d69 80ad348c 00000001 850dfc58 7750292a [ 4694.322695] 00000000 00000000 809c4374 ffff00fe 850dffe0 00001400 00000199 00000000 [ 4694.325083] ffffffff 866f7600 80a50000 878bd778 80a50000 80000000 809c2b50 00000000 [ 4694.326957] 00040cc0 00000000 000001d2 00000000 80a53220 7750292a 0000a098 80ad0000 [ 4694.327750] ...

Hi, Changes since V1: - the get_system_type() now will simply return the "system_type" variable if non-NULL, and the various boards can set this pointer should they want to set a custom value. The .get_system_type callback that v1 added to the struct mips_machine is gone. - the board-ingenic.c has been modified accordingly. - patch [06/13] is new, it makes sure that the kernel's command line is initialized properly and includes the parameters passed by the bootloader. - the cu1830-neo board defconfig has now been regenerated in patch [12/13].
