[U-Boot] [PATCH v2 00/27] spl: Use linker list and parameters for SPL image loading

[U-Boot] [PATCH v2 00/27] spl: Use linker list and parameters for SPL image loading

[Simon Glass]

At present the SPL code uses a global spl_image variable which is shared
amongst lots of files, some in common/spl and some elsewhere. There is no
need for this to be global, and in fact a parameter makes it easier to
understand what information the functions act on. It also reduces the BSS
use in the SPL (at the expense of stack) which is useful on boards which
don't have BSS available early on.

There are many global functions for loading images from each boot device
type, like spl_mmc_load_image() and spl_spi_load_image(). Mostly these take
the same parameters (none or a u32). There are various rules for compiling
in calls to these functions and in some cases somewhat different rules for
compiling in the functions themselves. For example, spl_spi_load_image() is
called if either of CONFIG_SPL_SPI_SUPPORT or CONFIG_SPL_SPI__FLASHSUPPORT
is enabled, but included in the image if CONFIG_SPL_SPI_LOAD is enabled.

There is work in progress to look at that problem (Andrew F. Davis has sent
some patches [1]), and this series does not address it. But even with that
fixed its seems better to use a linker list and a consistent function
signature for loading images.

This series converts spl_image into a parameter and moves the SPL load
functions into a linker list, where each method is declared in the file
that provides it. The existing dispatching code is dropped.

There is a priorty value attached to each loader which should allow the
existing ordering to be maintained.

Code size is about 20 bytes larger on average which I think is acceptable.
The BSS size drops by about 64 bytes, but really this just transfers to
the stack.

There is an obvious follow-on from this, to move boot_name_table[] into the
same linker list struct (i.e. add a name field to struct spl_image_loader).
The complication here is that we don't want naming if
CONFIG_SPL_LIBCOMMON_SUPPORT is not enabled, since it bloats the code. In
addition I think that common/spl/spl.c can be tidied up a little.

Finally, my reading of the load functions is that they could do with some
rationalisation once we have a way to init any device without
subsystem-specific function calls. For example, spl_sata.c and spl_usb.c
contain very similar code but for the init methods.

[U-Boot] [PATCH v2 01/27] spl: Move spl_board_load_image() into a generic header

[Simon Glass]

At present this is only used on ARM and sandbox, but it is just as
applicable to other architectures. Move the function prototype into the
generic SPL header.

[U-Boot] [PATCH v2 07/27] spl: Convert boot_device into a struct

[Simon Glass]

At present some spl_xxx_load_image() functions take a parameter and some
don't. Of those that do, most take an integer but one takes a string.

Convert this parameter into a struct so that we can pass all functions the
same thing. This will allow us to use a common function signature.

[U-Boot] [PATCH v2 08/27] spl: Add a way to declare an SPL image loader

[Simon Glass]

Add a linker list macro which can be used to declare an SPL image loader.
Update spl_load_image() to search available loaders for the correct one.

Signed-off-by: Simon Glass <sjg@chromium.org>

Changes in v2:
- Fix typo - rename spL_find_loader() to spl_ll_find_loader()

[U-Boot] [PATCH v2 18/27] spl: spi: Move the generic SPI loader into common/spl

[Simon Glass]

All the other SPL loaders are in this directory, so move the SPI one in
there too.

There are two board-specific SPI loaders (fsl and sunxi). These remain in
the drivers/mtd/spi directory, since they do not contain generic code.

[U-Boot] [PATCH v2 20/27] spi: Move freescale-specific code into a private header

[Simon Glass]

At present there are two SPI functions only used by freescale which are
defined in the spi_flash.h header. One function name matches an existing
generic SPL function.

Move these into a private header to avoid confusion.

Arcturus looks like it does not actually support SPI, so drop the SPI code
from that board.

[U-Boot] [PATCH v2 21/27] spl: Convert spl_net_load_image() to use linker list

[Simon Glass]

Add a linker list declaration for this method and remove the explicit
switch() code. We need two variants - one for BOOT_DEVICE_CPGMAC and one for
BOOT_DEVICE_USBETH.

[U-Boot] [PATCH v2 23/27] spl: Pass spl_image as a parameter to load_image() methods

[Simon Glass]

Rather than having a global variable, pass the spl_image as a parameter.
This avoids BSS use, and makes it clearer what the function is actually
doing.

[U-Boot] [PATCH v2 27/27] spl: Make spl_boot_list a local variable

[Simon Glass]

There is no need for this to be in the BSS region. By moving it we can delay
use of BSS in SPL. This is useful for machines where the BSS region is not
in writeable space. On 64-bit x86, SPL runs from SPI flash and it is easier
to eliminate BSS use than link SPL to run with BSS at a particular
cache-as-RAM (CAR) address.

Changes in v2:
- Add a memset() to clear the spl_image data
