From 0d76b71d93f6d7740b973dbb50010dc8f7b347f0 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Wed, 7 Oct 2020 15:13:17 +0200 Subject: [PATCH] arm64: zynqmp: Get rid of simple_itoa and replace it by snprintf simple_itoa() is implemented only for !CONFIG_USE_TINY_PRINTF. Tiny printf is normally used by SPL that's code which uses simple_itoa() has missing reference. That's why refactor code by using on snprintf() instead of strncpy()/strncat() combination. This change also descrease code size by saving 24B based on buildman. aarch64: (for 1/1 boards) all -22.0 rodata +2.0 text -24.0 xilinx_zynqmp_virt: all -22 rodata +2 text -24 u-boot: add: 0/0, grow: 0/-1 bytes: 0/-24 (-24) function old new delta board_init 520 496 -24 Signed-off-by: Michal Simek --- board/xilinx/zynqmp/zynqmp.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/board/xilinx/zynqmp/zynqmp.c b/board/xilinx/zynqmp/zynqmp.c index 70d6fd4..362c6e3 100644 --- a/board/xilinx/zynqmp/zynqmp.c +++ b/board/xilinx/zynqmp/zynqmp.c @@ -190,6 +190,7 @@ static char *zynqmp_get_silicon_idcode_name(void) u32 idcode, idcode2; char name[ZYNQMP_VERSION_SIZE]; u32 ret_payload[PAYLOAD_ARG_CNT]; + int ret; xilinx_pm_request(PM_GET_CHIPID, 0, 0, 0, 0, ret_payload); @@ -216,8 +217,10 @@ static char *zynqmp_get_silicon_idcode_name(void) return "unknown"; /* Add device prefix to the name */ - strncpy(name, "zu", ZYNQMP_VERSION_SIZE); - strncat(&name[2], simple_itoa(zynqmp_devices[i].device), 2); + ret = snprintf(name, ZYNQMP_VERSION_SIZE, "zu%d", + zynqmp_devices[i].device); + if (ret <= 0) + return "unknown"; if (zynqmp_devices[i].variants & ZYNQMP_VARIANT_EV) { /* Devices with EV variant might be EG/CG/EV family */ -- 2.7.4
