From 7d8073e7cfe0397137b5c13ceda876d4ca7875d6 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 17 Jul 2020 10:46:19 +0900 Subject: [PATCH] fdt_support: skip MTD node with "disabled" in fdt_fixup_mtdparts() Currently, fdt_fixup_mtdparts() only checks the compatible property. It is pointless to fix up the disabled node. Skip the node if it has the property: status = "disabled" Signed-off-by: Masahiro Yamada Reviewed-by: Simon Glass --- common/fdt_support.c | 17 ++++++++++------- 1 file changed, 10 insertions(+), 7 deletions(-) diff --git a/common/fdt_support.c b/common/fdt_support.c index 9c84702b19..a565b470f8 100644 --- a/common/fdt_support.c +++ b/common/fdt_support.c @@ -955,9 +955,16 @@ void fdt_fixup_mtdparts(void *blob, const struct node_info *node_info, for (i = 0; i < node_info_size; i++) { idx = 0; - noff = fdt_node_offset_by_compatible(blob, -1, - node_info[i].compat); - while (noff != -FDT_ERR_NOTFOUND) { + noff = -1; + + while ((noff = fdt_node_offset_by_compatible(blob, noff, + node_info[i].compat)) >= 0) { + const char *prop; + + prop = fdt_getprop(blob, noff, "status", NULL); + if (prop && !strcmp(prop, "disabled")) + continue; + debug("%s: %s, mtd dev type %d\n", fdt_get_name(blob, noff, 0), node_info[i].compat, node_info[i].type); @@ -973,10 +980,6 @@ void fdt_fixup_mtdparts(void *blob, const struct node_info *node_info, if (fdt_node_set_part_info(blob, noff, dev)) return; /* return on error */ } - - /* Jump to next flash node */ - noff = fdt_node_offset_by_compatible(blob, noff, - node_info[i].compat); } } } -- 2.39.5
