Kconfig: Varios: Fix more SPL, TPL dependencies

2019-08-26T15:46:29+00:00

Several options are presenting themselves on a various boards
where the options are clearly not used.  (ie, SPL/TPL options
when SPL or TPL are not defined)

This patch is not attempting to be a complete list of items, but
more like low hanging fruit.  In some instances, I wasn't sure
of DM was required, so I simply made them SPL or TPL.

This patch attempts to reduce some of the menuconfig noise
by defining dependencies so they don't appear when not used.

riscv: support SPL stack and global data relocation

2019-08-26T08:07:42+00:00

To support relocation of the stack and global data on RISC-V, the
secondary harts must be notified of the change using IPIs. We can reuse
the hart relocation code for this purpose. It uses global data to store
the new stack pointer and global data pointer for the secondary harts.
This means that we cannot update the global data pointer of the main
hart in spl_relocate_stack_gd(), because the secondary harts have not
yet been relocated at this point. It is updated after the secondary
harts have been notified.

spl: support booting via RISC-V OpenSBI

2019-08-26T08:07:42+00:00

RISC-V OpenSBI is an open-source implementation of the RISC-V Supervisor
Binary Interface (SBI) specification. It is required by Linux and U-Boot
running in supervisor mode. This patch adds support for booting via the
OpenSBI FW_DYNAMIC firmware. It supports OpenSBI version 0.4 and higher.

In this configuration, U-Boot SPL starts in machine mode. After loading
OpenSBI and U-Boot proper, it will start OpenSBI. All necessary
parameters are generated by U-Boot SPL and are passed to OpenSBI. U-Boot
proper is started in supervisor mode by OpenSBI. Support for OpenSBI is
enabled with CONFIG_SPL_OPENSBI. An additional configuration entry,
CONFIG_SPL_OPENSBI_LOAD_ADDR, is used to specify the load address of the
OpenSBI firmware binary. It is not used directly in U-Boot and instead
is intended to make the value available to scripts such as FIT
configuration generators.

The header file include/opensbi.h is based on header files from the
OpenSBI project. They are recent, as of commit bae54f764570 ("firmware:
Add fw_dynamic firmware").

spl: fit: use U-Boot device tree when FIT image has no device tree

2019-08-26T08:07:42+00:00

As part of the SPL FIT boot flow, the device tree is appended to U-Boot
proper. The device tree is used to record information on the loadables
to make them available to the SPL framework and U-Boot proper. Depending
on the U-Boot device tree provider, the FIT image might not include a
device tree. Information on the loadables is missing in this case.

When booting via firmware bundled with the FIT image, U-Boot SPL loads
the firmware binary and U-Boot proper before starting the firmware. The
firmware, in turn, is responsible for starting U-Boot proper.
Information on the memory location of the U-Boot proper loadable must be
available to the SPL framework so that it can be passed to the firmware
binary. To support this use case when no device tree is found in the FIT
image, fall back to the U-Boot device tree in this situation.

At the same time, update the comment to remove the note that the
destination address must be aligned to ARCH_DMA_MINALIGN. Alignment is
only required as an intermediate step when reading external data. This
is automatically handled by spl_fit_append_fdt(). After reading the
external data, it is copied to the specified address, which does not
have to be aligned to ARCH_DMA_MINALIGN.

env: Drop environment.h header file where not needed

This header file is now only used by files that access internal
environment features. Drop it from various places where it is not needed.

Move these functions to the new header file and rename set_default_env()
to env_set_default() so that it has a consistent env_ prefix.
