kbuild: Remove uncmd_spl logic

2022-12-23T15:15:13+00:00

At this point in the conversion there should be no need to have logic to
disable some symbol during the SPL build as all symbols should have an
SPL counterpart.

The main real changes done here are that we now must make proper use of
CONFIG_IS_ENABLED(DM_SERIAL) rather than many of the odd tricks we
developed prior to CONFIG_IS_ENABLED() being available.

Finish converting CONFIG_BOOTM_NETBSD et al to Kconfig

2022-04-01T14:28:45+00:00

This converts the following to Kconfig:
   CONFIG_BOOTM_NETBSD
   CONFIG_BOOTM_RTEMS
   CONFIG_DESIGNWARE_WATCHDOG
   CONFIG_DISPLAY_CPUINFO
   CONFIG_DM_ETH
   CONFIG_DM_MMC
   CONFIG_DM_REGULATOR
   CONFIG_DM_SPI
   CONFIG_DM_SPI_FLASH
   CONFIG_ISO_PARTITION
   CONFIG_OF_SEPARATE
   CONFIG_SPI_FLASH_WINBOND
   CONFIG_SPL_ETH
   CONFIG_TIMER
   CONFIG_USB_DWC3
   CONFIG_USB_DWC3_GADGET
   CONFIG_USB_DWC3_OMAP
   CONFIG_USB_DWC3_PHY_OMAP
   CONFIG_USB_EHCI_TEGRA
   CONFIG_USB_GADGET_DOWNLOAD
   CONFIG_USB_GADGET_DUALSPEED
   CONFIG_USB_GADGET_MANUFACTURER
   CONFIG_USB_GADGET_PRODUCT_NUM
   CONFIG_USB_GADGET_VBUS_DRAW
   CONFIG_USB_GADGET_VENDOR_NUM

This catches a number of cases where board config files were #undef
various CONFIG options when building SPL, and that doesn't work.  Clean
up the related comments as well.

dm: core: Allow dm_warn() to be used in SPL

2020-10-29T20:42:17+00:00

At present this option is disabled in SPL, meaning that warnings are not
displayed. It is sometimes useful to see warnings in SPL for debugging
purposes.

Add a new Kconfig option to permit this.

dm: gpio: Allow control of GPIO uclass in SPL

2019-12-15T00:52:29+00:00

At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass
is included in SPL/TPL without any control for boards. Some boards may
want to disable this to reduce code size where GPIOs are not needed in
SPL or TPL.

Add a new Kconfig option to permit this. Default it to 'y' so that
existing boards work correctly.

Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to
preserve the current behaviour. Also update the 74x164 GPIO driver since
it cannot build with SPL.

This allows us to remove the hacks in config_uncmd_spl.h and
Makefile.uncmd_spl (eventually those files should be removed).

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

configs: Re-sync almost all of cmd/Kconfig

2016-04-25T19:09:40+00:00

This syncs up the current cmd/Kconfig and include/configs/ files with the
only exception being CMD_NAND.  Due to how we have used this historically
we need to take further care here when converting.

spl: dm: Add SPL_DM_SEQ_ALIAS config option

2016-01-13T12:20:02+00:00

The Device Model sequence alias feature is required by some Uclasses.
Instead of disabling the feature for all SPL targets allow it to be
configured.

The config option is disabled by default to reduce code size for targets
that are not interested or do not require this feature.

of: clean up OF_CONTROL ifdef conditionals

2015-08-18T17:46:05+00:00

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.  We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:

 #ifdef CONFIG_OF_CONTROL
 # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
 #  define OF_CONTROL 0
 # else
 #  define OF_CONTROL 1
 # endif
 #else
 # define OF_CONTROL 0
 #endif

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute.  It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.

Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

of: flip CONFIG_SPL_DISABLE_OF_CONTROL into CONFIG_SPL_OF_CONTROL

2015-08-18T17:46:04+00:00

As we discussed a couple of times, negative CONFIG options make our
life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ...
and here is another one.

Now, there are three boards enabling OF_CONTROL on SPL:
 - socfpga_arria5_defconfig
 - socfpga_cyclone5_defconfig
 - socfpga_socrates_defconfig

This commit adds CONFIG_SPL_OF_CONTROL for them and deletes
CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert
the logic.

dm: drop CONFIG_DM_DEVICE_REMOVE from uncmd list

2015-08-18T17:46:04+00:00

We do not want to compile the DM remove code for SPL.  Currently,
we undef it in include/config_uncmd_spl.h (for C files) and in
scripts/Makefile.uncmd_spl (for Makefiles).  This is really ugly.

This commit demonstrates how we can deprecate those two files.

Use $(SPL_) for the entry in the Makfile and CONFIG_IS_ENABLED()
in C files.
