This bug appears in b6396403 which makes u-boot unable to pass
arguments via bootm to a standalone application without this patch.
Steps to reproduce.
Compile a u-boot. Use mkimage to package the standalone hello_world.bin
file.
e.g. For the MIPS Boston platform
mkimage -n "hello" -A mips -O u-boot -C none -T standalone \
-a 0xffffffff80200000 -d hello_world.bin \
-ep 0xffffffff80200000 hello_out
Then tftp hello_out and run it using
boston # dhcp 192.168.154.45:hello_out
...
boston # bootm $loadaddr 123 321
Without the patch the following output is observed.
boston # bootm $loadaddr 123 321
Image Name: hello
Image Type: MIPS U-Boot Standalone Program (uncompressed)
Data Size: 1240 Bytes = 1.2 KiB
Load Address: 80200000
Entry Point: 80200000
Verifying Checksum ... OK
Loading Standalone Program ... OK
Example expects ABI version 8
Actual U-Boot ABI version 8
Hello World
argc = 0
argv[0] = "0xffffffff88000000"
With the patch, you see the following.
boston # bootm $loadaddr 123 321
Image Name: hello
Image Type: MIPS U-Boot Standalone Program (uncompressed)
Data Size: 1240 Bytes = 1.2 KiB
Load Address: 80200000
Entry Point: 80200000
Verifying Checksum ... OK
Loading Standalone Program ... OK
Example expects ABI version 8
Actual U-Boot ABI version 8
Hello World
argc = 3
argv[0] = "0xffffffff88000000"
argv[1] = "123"
argv[2] = "321"
argv[3] = "<NULL>"
Without the patch, the go command at the entry point seems to work.
boston # go 0xffffffff80200000 123 321
Example expects ABI version 8
Actual U-Boot ABI version 8
Hello World
argc = 3
argv[0] = "0xffffffff80200000"
argv[1] = "123"
argv[2] = "321"
argv[3] = "<NULL>"
