	The below 7000+ cmds take a KeySource (equivalent to NX-GenerateAesKey) and an u32. Bitmask 0x1F of the u32 is the Generation, 0x20 is valid but doesn't seem to do anything. Values >=0x21 throw error. A 0x10-byte outbuf is used for the output key. Cmd7004/Cmd7005 use a 0x20-byte outbuf. These are equivalent to GenerateAesKek+GenerateAesKey combined.		The below 7000+ cmds take a KeySource (equivalent to NX-GenerateAesKey) and an u32. Bitmask 0x1F of the u32 is the Generation, 0x20 is valid but doesn't seem to do anything.

			With Nx commands, valid key generations match what's expected for S1. With Ounce commands, the valid key generations on 20.x are 0/1.

	All of these use AES-ECB with the input KeySource, with the buffer as the output.		All of these use AES-ECB with the input KeySource, with the buffer as the output.
