[U-Boot] cmd_sf warning on size_t

[U-Boot] cmd_sf warning on size_t

[Thomas Chou]

Hi Mike,

I got this warning on cmd_sf.c,

cmd_sf.c: In function `spi_flash_update_block':
cmd_sf.c:130: warning: unsigned int format, size_t arg (arg 4)
cmd_sf.c:135: warning: unsigned int format, size_t arg (arg 3)


It was related to our arch/avr32|blackfin|nios2/asm/posix_types.h
typedef unsigned long __kernel_size_t;

While most other 32 bits archs use unsigned int, we three use unsigned long.

It is said in linux-2.6/include/asm-generic/posix_types.h
/*
  * Most 32 bit architectures use "unsigned int" size_t,
  * and all 64 bit architectures use "unsigned long" size_t.
  */

Shall we fix the cmd_sf.c, or shall I change size_t to unsigned int as 
other 32 bits archs do?

Best regards,
Thomas

I tumble over this these days too.

I tend to fix the cmd_sf.c and arch/avr32/cpu/at32ap700x/mmu.c
->
mmu.c:25: warning: format '%08x' expects type 'unsigned int', but
argument 2 has type 'uintptr_t'

I have already a patch, and would send it.

[U-Boot] [PATCH/RFC] fix several printf() modifiers

[Andreas Bießmann]

From: Andreas Bie?mann <biessmann@corscience.de>

Some architectures define size_t to unsigned long even though they are 32 bit
architectures.

This patch fixes several warnings when running MAKEALL for avr32 architecture:

---8<---
mmu.c: In function 'mmu_init_r':
mmu.c:25: warning: format '%08x' expects type 'unsigned int', but argument 2 has type 'uintptr_t'
fat.c: In function 'do_fat_read':
fat.c:879: warning: format '%d' expects type 'int', but argument 4 has type 'long unsigned int'
cmd_sf.c: In function 'spi_flash_update_block':
cmd_sf.c:130: warning: format '%#x' expects type 'unsigend int', but argument 4 has type 'size_t'
cmd_sf.c:135: warning: format '%x' expects type 'unsigned int', but argument 3 has type 'size_t'

Hi Andreas,

Thanks. I have tested cmd_sf and fat.

Tested-by: Thomas Chou <thomas@wytron.com.tw>

I would suggest splitting this patch into three, as they related to 
different custodians.

No, that is not true - the patch is a single logical unit

The three maintainers can each provide an Ack

this isn't the same.  probably should be %08lx.

You are right, but as you may know the memory map for at32ap7000 has its
SDRAM physically at 0x10000000. Therefore the result will be the same
for 0x%08lx and %#lx (in all currently available boards).
But maybe one will locate the vmr_table sometimes in SRAM some day?

I will provide v2 which change this back, split off in three patches and
add the respective custodian in cc.

i don't know anything about AVR32 ;)

> But maybe one will locate the vmr_table sometimes in SRAM some day?

seems safer, although probably unlikely as i think the AVR32 is pretty much 
dead nowadays ?
