Otherwise cronus putmem fails istep and BML fails to upload skiboot To do that, we still use our one-page command buffer for small commands for speed, and for anything bigger, with a limit of 1MB plus a page, we vmalloc a temporary buffer. The limit was chosen because Cronus will break up any data transfer into 1M chunks (the extra page is for the command header).
