spl: spl_legacy: Add lzma decompression support for legacy image

2020-04-27T18:29:33+00:00

This patch adds support for decompressing LZMA compressed u-boot payload
in legacy uImage format.

Using this patch together with u-boot-lzma.img may be useful for some
platforms as they can reduce the size and load time of u-boot payload.

spl: spl_nor: Remove unused variable 'ret' warning

2020-04-27T18:29:33+00:00

With the if statement now for the legacy image handling, the compiler
now generates this compile time warning:

common/spl/spl_nor.c:27:6: warning: unused variable 'ret' [-Wunused-variable]

This patch removes this warning by changing the 'ret' variable handling.

spl: spl_nor: Move legacy image loading into spl_legacy.c

2020-04-27T18:29:33+00:00

Move the legacy image loading into spl_legacy.c. This makes it easier
to extend the legacy image handling with new features that other
SPL loaders might use (e.g. spl_spi.c etc).

No functional change intended.

2020-04-27T18:29:33+00:00

This patch moves the legacy image handling into a separate file, which
will be extended with other legacy image features later.

No function change intended.

spl: fit: do not check argument of free()

2020-04-24T20:40:09+00:00

The free() function checks if its argument is NULL. It is superfluous to do
the same check on the calling side.

spl: Kconfig: de-dup SPL_DM_GPIO definition

2020-04-24T14:51:32+00:00

Two nearly concurrent commits (d4d65e112 and bcee8d676) added a
SPL_DM_GPIO symbol. Resolve the duplication in favor of the version
in drivers/gpio/Kconfig.

riscv: Introduce SPL_SMP Kconfig option for U-Boot SPL

2020-04-23T02:14:06+00:00

With SBI v0.2 HSM extension, only a single hart need to boot and
enter operating system. The booting hart can bring up secondary
harts one by one afterwards.

For U-Boot running in SPL, SMP can be turned on, while in U-Boot
proper, SMP can be optionally turned off if using SBI v0.2 HSM.

Introduce a new SPL_SMP Kconfig option to support this.

spl: mmc: Rename spl_boot_partition() to spl_mmc_boot_partition()

2020-04-22T12:41:57+00:00

This function is only relevant to the MMC driver so calling it
spl_boot_partition() might be confusing.  Rename it to
spl_mmc_boot_partition() to make its purpose more clear (and bring
it in line with spl_mmc_boot_mode()).

spl: mmc: Rename spl_boot_mode() to spl_mmc_boot_mode()

2020-04-22T12:41:57+00:00

The function's name is misleading as one might think it is used
generally to select the boot-mode when in reality it is only used by the
MMC driver to find out in what way it should try reading U-Boot Proper
from a device (either using a filesystem, a raw sector/partition, or an
eMMC boot partition).

Rename it to spl_mmc_boot_mode() to make it more obvious what this
function is about.
