From: Michael Tokarev Date: Sat, 03 Aug 2024 11:18:58 +0300 Subject: u-boot-sam460ex: build fixes Forwarded: https://lists.nongnu.org/archive/html/qemu-devel/2025-01/msg00767.html Fixes or works around numerous build issues and one real bug. Most are due to new defaults in gcc (in debian), like -Werror=implicit-function-declarations (there are a lot of missing decls) -Werror=incompatible-pointer-types (function types mismatches) -Werror=int-conversion (free int <=> pointer conversion) Bug-Debian: https://bugs.debian.org/1075428 Signed-off-by: Michael Tokarev diff --git a/roms/u-boot-sam460ex/board/ACube/Sam460ex/Sam460ex.c b/roms/u-boot-sam460ex/board/ACube/Sam460ex/Sam460ex.c index 4d5b953c02..5ecf16dbe2 100644 --- a/roms/u-boot-sam460ex/board/ACube/Sam460ex/Sam460ex.c +++ b/roms/u-boot-sam460ex/board/ACube/Sam460ex/Sam460ex.c @@ -843,7 +843,7 @@ int last_stage_init (void) // cleanup last 8 bytes of the RTC registers bank ----- char arr[8] = { 0 }; - i2c_write(0x68, 0x08, 1, &arr, 8); + i2c_write(0x68, 0x08, 1, arr, 8); // USB Init ------------------------------------------- diff --git a/roms/u-boot-sam460ex/common/usb.c b/roms/u-boot-sam460ex/common/usb.c index 203c9f7795..d645d36c8e 100644 --- a/roms/u-boot-sam460ex/common/usb.c +++ b/roms/u-boot-sam460ex/common/usb.c @@ -957,7 +957,7 @@ void usb_scan_devices(void) printf("%d USB Device(s) found\n", dev_index); #ifdef CONFIG_SAM460EX - static attempts = 0; + static int attempts = 0; if (dev_index < 3) { u16 fpga_val = in_be16((void *)CONFIG_SYS_FPGA_BASE + 0x2E); diff --git a/roms/u-boot-sam460ex/config.mk b/roms/u-boot-sam460ex/config.mk index bcda77611a..9928f5f4c6 100644 --- a/roms/u-boot-sam460ex/config.mk +++ b/roms/u-boot-sam460ex/config.mk @@ -191,6 +191,11 @@ endif CFLAGS += $(call cc-option,-fno-stack-protector) +# this u-boot is an old bad code +CFLAGS += $(call cc-option,-Wno-error=implicit-function-declaration) +CFLAGS += $(call cc-option,-Wno-error=incompatible-pointer-types) +CFLAGS += $(call cc-option,-Wno-error=int-conversion) + # $(CPPFLAGS) sets -g, which causes gcc to pass a suitable -g # option to the assembler.
