treewide: Use OF_REAL instead of !OF_PLATDATA

2021-09-25T15:46:15+00:00

Now that we have a 'positive' Kconfig option, use this instead of the negative one, which is harder to understand. Signed-off-by: Simon Glass

spi: ich: Limit slave->max_read_size

2021-08-02T07:11:40+00:00

Since commit 43c145b8b3ee ("spi: ich: Correct max-size bug in ich_spi_adjust_size()") (in v2020.04-rc1), SPI flash read no longer works with ICH SPI controller in software sequencer mode. ICH controller can only transfer a small number of bytes at once. Before commit 43c145b8b3ee, the logic happens to make sure data.nbytes is limited to slave->max_write_size but after commit 43c145b8b3ee data.nbytes is no longer limited because slave->max_read_size is not initialized with a valid number.

spi: ich: Don't require the PCH

2021-07-15T11:49:52+00:00

When booting from coreboot we may not have a PCH driver available. The SPI driver can operate without the PCH but currently complains in this case. Update it to continue to work normally. The only missing feature is memory-mapping of SPI-flash contents, which is not essential. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Reviewed-by: Jagan Teki

x86: spl: Move priv/plat structs to headers

2021-01-05T19:24:41+00:00

With the new of-platdata, these need to be available to dt_platdata.c so must be in header files. Move them. Signed-off-by: Simon Glass

dm: treewide: Rename ..._platdata variables to just ..._plat

2020-12-13T23:51:09+00:00

Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass

dm: treewide: Rename ofdata_to_platdata() to of_to_plat()

2020-12-13T23:51:09+00:00

This name is far too long. Rename it to remove the 'data' bits. This makes it consistent with the platdata->plat rename. Signed-off-by: Simon Glass

dm: treewide: Rename dev_get_platdata() to dev_get_plat()

2020-12-13T23:51:09+00:00

Rename this to be consistent with the change from 'platdata'. Signed-off-by: Simon Glass

dm: treewide: Rename 'platdata' variables to just 'plat'

2020-12-13T23:51:08+00:00

We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25+00:00

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass

x86: apl: Enable SPI flash in TPL with APL_SPI_FLASH_BOOT

2020-10-29T20:42:18+00:00

At present, enabling CONFIG_APL_SPI_FLASH_BOOT does not build since SPI and SPI flash are not enabled for TPL. Add a condition to fix this and tidy up a build warning in the SPI-flash driver. Signed-off-by: Simon Glass
