Texas Instruments Keystone family of multicore devices now includes an

Subsequent patches in this series will extend support to include SMP and take
advantage of the large physical memory addressing capabilities via LPAE.

Thanks for taking a look, Arnd.

Any inputs on the other patches in this series? I'd ideally like to have the LPAE fixes, and code patching changes merged in sooner than the Keystone machine specific stuff.

And some nitpicking:

+ bootargs = "console=ttyS0,115200n8 debug earlyprintk lpj=50000 rdinit=/bin/ash rw root=/dev/ram0 initrd=0x85000000,9M";
+ };

This command line should not really be here. Most of what you put in it is not
generic to the platform at all.

In order to select the console, use an alias for the serial device.


Agreed. The DTS in general needs quite a bit of work.

+static void __init keystone_map_io(void)
+{
+ iotable_init(io_desc, sizeof(io_desc)/sizeof(struct map_desc));
+}

Use the ARRAY_SIZE macro here.


Thanks. I've fixed this in the code, and this will show up in the next rev.
