Commit 40686c394e ("riscv: Clean up IPI initialization code")
caused U-Boot failed to boot on SiFive HiFive Unleashed board.
The codes inside arch_cpu_init_dm() may call U-Boot timer APIs
before the call to riscv_init_ipi(). At that time the timer register
base (e.g.: the SiFive CLINT device in this case) is unknown yet.
It might be the name riscv_init_ipi() that misleads people to only
consider it is related to IPI, but in fact the timer capability is
provided by the same SiFive CLINT device that provides the IPI.
Timer capability is needed for both UP and SMP.
Considering that the original refactor does have benefits, that it
makes the IPI code more similar to U-Boot initialization idioms.
It also removes some quite ugly macros. Let's do the minimal revert
instead of a complete revert, plus a fixes to arch_cpu_init_dm() to
consider the SPL case.

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.
The semantic patch that makes this change is as follows:

This change allows more fine tuning of driver model based SPI support in
SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI
support in SPL and TPL via Kconfig option.
Before this change it was necessary to use:
/* SPI Flash Configs */
#if defined(CONFIG_SPL_BUILD)
#undef CONFIG_DM_SPI
#undef CONFIG_DM_SPI_FLASH
#undef CONFIG_SPI_FLASH_MTD
#endif
in the ./include/configs/<board>.h, which is error prone and shall be
avoided when we strive to switch to Kconfig.
The goal of this patch:
Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL).
Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must
still support non DM driver.
Another use case is the conversion of non DM/DTS SPI driver to support
DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the
distinction is needed in Kconfig (also if SPL version of the driver
supports OF_PLATDATA).
In the end of the day one would have to support following use cases (in
single driver file - e.g. mxs_spi.c):
- U-Boot proper driver supporting DT/DTS
- U-Boot proper driver without DT/DTS support (deprecated)
- SPL driver without DT/DTS support
- SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to
run full blown DT/DTS)
- SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained
environment with no fitImage and OF_LIBFDT support).
Some boards do require SPI support (with DM) in SPL (TPL) and some only
have DM_SPI{_FLASH} defined to allow compiling SPL.
This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI)
and provides corresponding defines in Kconfig.

For Allwinner SoCs the CONFIG_SYS_SPI_U_BOOT_OFFS value is not really a
board choice: The boot ROM only loads the SPL from offset 0 of the SPI
NOR flash, and loads at most 32KB. This is a similar situation as on MMC,
so consequently we create our "joint" image (SPL + U-Boot proper) with
that 32KB offset during the build.
So define the value of this symbol to be 32KB by default for every
Allwinner SoC. This removes the definition of this symbol from the

- Clearfog: Fix SD booting (Baruch)
- Misc updates to MMC handling in SPL to support booting from
main data partition (vs hardware boot partition) on MVEBU (Baruch)
On Armada 38x platforms the ROM code loads SPL from offset 0 of eMMC
hardware boot partitions. When there are no boot partitions (i.e. SD
card) the ROM skips the first sector that usually contains the (logical)
partition table. Since the generated .kwb image contains the main U-Boot
image in a fixed location (0x140 sectors by default), we end up with the
main U-Boot image in offset of 1 sector. The current workaround is to
manually set CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR to 0x141 to
compensate for that.
This patch uses the run-time detected boot partition to determine the
right offset of the main U-Boot partition. The generated .kwb image is
now compatible with both eMMC boot partition, and SD card main data
partition.

Add a wait option to smp_call_function() to wait for the secondary harts
to acknowledge the call-function request. The request is considered to
be acknowledged once each secondary hart has cleared the corresponding
IPI.
As part of the call-function request, the secondary harts invalidate the
instruction cache after clearing the IPI. This adds a delay between
acknowledgment (clear IPI) and fulfillment (call function) of the
request. We want to use the acknowledgment to be able to judge when the
request has been completed. Remove the delay by clearing the IPI after
cache invalidation and just before calling the function from the
request.

OpenSBI uses a relocation lottery to determine the hart to relocate
OpenSBI to its link address. In the U-Boot SPL boot flow, the main hart
schedules the secondary harts to enter OpenSBI before doing so itself.
One of the secondary harts will therefore always be the winner of the
relocation lottery. This is problematic if the link address ranges of
OpenSBI and U-Boot SPL overlap. OpenSBI will be relocated and therefore
overwrite U-Boot SPL while some harts may still run it, leading to code
corruption.
Avoid this problem by specifying the main hart as the preferred boot
hart to perform the OpenSBI relocation. The main hart will be the last
hart to enter OpenSBI, relocation can therefore occur safely.
The boot hart field was added to version 2 of the OpenSBI FW_DYNAMIC
info structure. The header file include/opensbi.h is synchronized with
include/sbi/fw_dynamic.h from the OpenSBI project to update the info
structure. The header file is recent as of commit
7a13beb21326 ("firmware: Add preferred boot HART field in struct
fw_dynamic_info").

At the moment entry_point is set to image_get_load(header) that sets it
to "load address" instead of "entry point", assuming entry_point is
equal to load_addr, but it's not true. Then load_addr is set to
"entry_point - header_size", but this is wrong too since load_addr is
not an entry point.
So use image_get_ep() for entry_point assignment and image_get_load()
for load_addr assignment.

On i.MX8, when booting from eMMC boot partition, the whole flash.bin
is stored in boot partition, however SPL switches to user partition
during the init of mmc driver:
spl_mmc_load() -> mmc_init()
Then it tries to load the container image in
spl_mmc_get_uboot_raw_sector(), but here it reads the data from user
partition and the header is not recognized as a valid header.
So we move spl_mmc_get_uboot_raw_sector after eMMC partition switch
to address this issue.
Anyway put spl_mmc_get_uboot_raw_sector before eMMC partition switch
is not correct, so let's move it after eMMC partition switch.

Signed-off-by: Andreas Dannenberg <dannenberg@ti.com>
During FIT reading through ymodem_read_fit() the function
xyzModem_stream_read() is being used which returns zero once the end
of a stream has been reached. This could lead to an premature exit from
ymodem_read_fit() with certain-sized FIT images reporting that zero
bytes overall were read. Such a premature exit would then result in an
-EIO failure being triggered within the spl_load_simple_fit() caller
function and ultimately lead to a boot failure.
Fix this logic by simply aborting the stream read loops and continuing
with the regular code flow which ultimately would lead to returning
the number of bytes to be read ('size') as expected by the callers of
ymodem_read_fit().

In SPL, all the available mmc devices gets initialized during boot.

certain mmc devices(other than boot device) and the support for
enabling device might not be ready.
Texas Instruments' K3 J721E device having a central system controller
(dmsc) is one such example falling in this category. Below is the
sequence for the failing scenario:
- ROM comes up in SD mode and loads SPL by just initialing SD card.
- SPL loads dmsc firmware from SD Card.
Since ROM has enabled SD, SPL need not enable the SD, just need
to re initialize the card. But SPL is trying to initialize other MMC
instances which are in disabled state. Since dmsc firmware is not yet
available, devices cannot be enabled. So in SPL, initialize only the
mmc device that is needed.

This change tries to fix the following problem:
- The board boots (to be more precise - ROM loads SPL) from a slow SPI-NOR
memory.
As a result the spl_boot_device() will return SPI-NOR as a boot device
(which is correct).
- The problem is that in 'falcon boot' the eMMC is used as a boot medium to
load kernel from its partition.
Calling spl_boot_device() will break things as it returns SPI-NOR device.
To fix this issue the new CONFIG_SPL_FORCE_MMC_BOOT Kconfig flag is
introduced to handle this special use case. By default it is not defined,
so there is no change in the legacy code flow.

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").

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.

Several options are presenting themselves on a various boards
where the options are clearly not used. (ie, arm64 options on
arm9, or 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.
This patch attempts to reduce some of the menuconfig noise
by defining dependencies so they don't appear when not used.

This implements a stack usage check in SPL.
Many boards start up SPL to run code + data from one common, rather small
SRAM. To implement a sophisticated SPL binary size limit on such boards,
the stack size (as well as malloc size and global data size) must be
subtracted from this SRAM size.
However, to do that properly, the stack size first needs to be known.
This patch adds a new Kconfig option:
- SPL_SYS_REPORT_STACK_F_USAGE: memset(0xaa) the whole area of the stack
very early and check stack usage based on this constant later before the
stack is switched to DRAM
Initializing the stack and checking it is implemented in weak functions,
in case a board does not use the stack as saved in gd->start_addr_sp.
