[U-Boot] [PATCH v2] sf: remove spi-flash chip names from SPL binary
The table of spi flash chips 'spi_flash_ids' currently includes chip names. The only usage of these is to print the name when the chip is probed.
Since this message is not shown in SPL, we can remove the names from the SPL binary.
Removing the chip names saves ~890 Byte from the SPL binary in my configuration (socfpga_socrates_defconfig, MACRONIX, SPANSION and STMICRO enabled).
Signed-off-by: Simon Goldschmidt simon.k.r.goldschmidt@gmail.com
--- Changes in v2: - use CONFIG_SPL_BUILD directly instead of SPI_FLASH_INCLUDE_NAME - iterate spi_flash_ids list until info->sector_size == 0, remove the extra global 'const size_t spi_flash_ids_size'

The table of spi flash chips 'spi_flash_ids' currently includes chip names. The only usage of these is to print the name when the chip is probed.
Since this message is not shown in SPL, we can remove the names from the SPL binary.
Removing the chip names saves ~890 Byte from the SPL binary in my configuration (socfpga_socrates_defconfig, MACRONIX, SPANSION and STMICRO enabled).
I'm not still quite happy with this change, other than reducing the size which introduces many ifdef's what would you benefits with this 890bytes? do you have any room to add any key features in SPL?

Well, SPL is always tight, isn't it? Currently, I have ~7.5 kB free on my socfpga gen5 board. And to get the features required by management, I will have to add suppport for loading U-Boot from a FIT image and checking its signature.
Because of that, I figured saving RAM in SPL would be good. I don't know my required features fit in after applying this patch, though.
But if you don't like it, feel free to drop it. I don't have an immediate need to apply this.
