Hi!
I'm working on adding SPI driver for Atheros 933x.
I'm using this code for registering spi flash:
=========================================================
static struct flash_platform_data spi_boot_flash_data = {
.name = "spi",
.type = "s25sl032p",
};
static struct spi_board_info spi_devs[] __initdata = {
{
/* boot: Spansion S25FL032P SPI flash */
.name = "m25p80",
.max_speed_hz = 104 * 1000 * 1000,
.bus_num = 0,
.chip_select = 0,
.mode = SPI_MODE_3,
.platform_data = &spi_boot_flash_data,
},
};
...
spi_register_board_info(spi_devs, ARRAY_SIZE(spi_devs));
=========================================================
If I rebase Atheros 933x over barebox-2013.11.0 then this code
works fine.
If I rebase Atheros 933x over barebox-2013.12.0 then I get
"Ooops" in get_param_by_name(dev=spi, name=size)
=========================================
Board: TP Link WR720N
m25p80 m25p800: s25sl032p (4096 Kbytes)
register_device: already registered spi
Ooops, TLB miss on load or ifetch!
...
### ERROR ### Please RESET the board ###
=========================================
Changing this
=========================================================
static struct flash_platform_data spi_boot_flash_data = {
.name = "spi",
.type = "s25sl032p",
};
=========================================================
to
=========================================================
static struct flash_platform_data spi_boot_flash_data = {
.name = "spi0",
.type = "s25sl032p",
};
=========================================================
solves the problem.
Sascha, please, comment this message.
