Oliver O'Halloran 066bc3576e powerpc/xmon: Fix whitespace handling in getstring() ... The ls (lookup symbol) and zr (reboot) commands use xmon's getstring() helper to read a string argument from the xmon prompt. This function skips over leading whitespace, but doesn't check if the first "non-whitespace" character is a newline which causes some odd behaviour (<enter> indicates a the enter key was pressed): 0:mon> ls printk<enter> printk: c0000000001680c4 0:mon> ls<enter> printk<enter> Symbol ' printk' not found. 0:mon> With commit 2d9b332d99 ("powerpc/xmon: Allow passing an argument to ppc_md.restart()") we have a similar problem with the zr command. Previously zr took no arguments so "zr<enter> would trigger a reboot. With that patch applied a second newline needs to be sent in order for the reboot to occur. Fix this by checking if the leading whitespace ended on a newline: 0:mon> ls<enter> Symbol '' not found.
