This patch-set finish the previous serie: http://patchwork.ozlabs.org/project/uboot/list/?series=76834
and also replace the serie: "Remove defines for SPI default speed and mode " http://patchwork.ozlabs.org/project/uboot/list/?series=80769&state=*
This new version is a complete rework after several remarks and regression for these 2 patchset, mainly when SPI node configuration is not in DT, when platdata is used.
I take some time to check the code and this proposal is a rework of commit 96907c0fe50a ("dm: spi: Read default speed and mode values from DT")
This patch avoid spi_get_bus_and_cs() callers to force value of parameter speed to 0 for some board (without DT node) and regression for other board (as i was the case in my previous Series V2).
I see this kind of problem in file env/sf.c with first commit 96907c0fe50a ("dm: spi: Read default speed and mode values from DT") and come-back to the previous behavior with CONFIG_ in the commit 25a17652c9c2 ("fix: env: Fix the SPI flash device setup for DM mode")
So I decide to don't remove the defines used for default value of speed and mode but they are no more used when platdata is available.
That avoid regression when spi_get_bus_and_cs is directly called.
NB: I don't sure that the behavior of 'compatibility' function spi_setup_slave() will be still is still the correct on (in some case speed and mode will parameter will be not used).
Tested on my board only for the boot from SPI NOR so when spl_spi_load_image() is called in SPL.
Changes in v4: - rebase on v2019.04-rc2 - after Jagan review depends on Migrate SPI defines to Kconfig http://patchwork.ozlabs.org/project/uboot/list/?series=94485 - remove no more supported configuration: CONFIG_ENV_SPI_MAX_HZ=0 or CONFIG_ENV_SPI_MODE=0
Changes in v3: - complete rework of the patch-set to avoid regression
Changes in v2: - use variables to avoid duplicated code
