From 55fe0e2b54173ebdc2aa87c329750c2a70e84fb2 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Wed, 28 Feb 2018 20:51:43 +0100 Subject: [PATCH] spl: fix binman_sym output check A previous commit introduced the use of binman in the SPL. After the binman_sym call over the 'pos' symbol, the output value is checked against BINMAN_SYM_MISSING (-1UL). According to the documentation (tools/binman/README), when it comes to the 'pos' attribute: pos: This sets the position of an entry within the image. The first byte of the image is normally at position 0. If 'pos' is not provided, binman sets it to the end of the previous region, or the start of the image's entry area (normally 0) if there is no previous region. So instead of checking if the return value is BINMAN_SYM_MISSING, we should also check if the value is not null. The failure happens when using both the SPL file and the U-Boot file independently instead of the concatenated file (SPL + padding + U-Boot). This is because the U-Boot binary file alone does not have the U-Boot header while it is present in the concatenation file. Not having the header forces the SPL to discover where it should load U-Boot. The binman_sym call is supposed to do that but fails. Because of the wrong check, the destination address was set to 0 while it should have been somewhere in RAM. This, obviously, stalls the board.
