disk: honor CONFIG_SYS_64BIT_LBA

2022-07-02T12:19:09+00:00

Without the patch for qemu-x86_defconfig:

* sizeof(lbaint_t) = 4 in dev_read()
* sizeof(lbaint_t) = 8 in blkcache_read()

CONFIG_SYS_64BIT_LBA is defined in common.h via
include/configs/x86-common.h:22.

We have to include common.h before including blk.h.

disk: incorrect message in is_gpt_valid()

2022-05-28T08:59:27+00:00

alloc_read_gpt_entries() writes differentiated error messages.
The caller is_gpt_valid() should not write an extra possibly wrong message.

disk: part_efi: add support to repair gpt table

2022-05-06T18:39:15+00:00

If a gpt table is corrupted (after a power cut
for example), then the gpt table should repaired.
The function gpt_repair_headers check if at least
one gpt table is valid, and then only write the
corrupted gpt table.

dm: disk: add read/write interfaces with udevice

2022-04-23T20:05:41+00:00

In include/blk.h, Simon suggested:
===>
/*
 * These functions should take struct udevice instead of struct blk_desc,
 * but this is convenient for migration to driver model. Add a 'd' prefix
 * to the function operations, so that blk_read(), etc. can be reserved for
 * functions with the correct arguments.
 */
unsigned long blk_dread(struct blk_desc *block_dev, lbaint_t start,
                        lbaint_t blkcnt, void *buffer);
unsigned long blk_dwrite(struct blk_desc *block_dev, lbaint_t start,
                         lbaint_t blkcnt, const void *buffer);
unsigned long blk_derase(struct blk_desc *block_dev, lbaint_t start,
                         lbaint_t blkcnt);
<===

So new interfaces are provided with this patch.

They are expected to be used everywhere in U-Boot at the end.
The exceptions are block device drivers, partition drivers and efi_disk
which should know details of blk_desc structure.

dm: disk: add UCLASS_PARTITION

2022-04-23T20:05:41+00:00

NOTE: probably we have to update config dependencies,
in particular, SPL/TPL_PRINTF?

With this new function, UCLASS_PARTITION devices will be created as
child nodes of UCLASS_BLK device.

disk: don't compile in partition support for spl/tpl if not really necessary

2022-04-23T20:05:34+00:00

Under the current Kconfigs, disk/part.c will be compiled in even if none of
partition table types are enabled. This will lead to the size growth of SPL
/TPL code.

With this patch, CONFIG_PARTITIONS is selected only if, at least, one of
CONFIG_*_PARTITION is enabled.

disk: Correct the conditions for SPL

These filesystems may have different settings for SPL and TPL. Use the
correct Makefile variable to handle this.

fs: Add semihosting filesystem

2022-04-01T19:03:13+00:00

This adds a filesystem which is backed by the host's filesystem. It is
modeled off of sandboxfs, which has very similar aims. Semihosting
doesn't support listing directories (except with SYS_SYSTEM), so neither
do we. it's possible to optimize a bit for the common case of reading a
whole file by omitting a call to smh_seek, but this is left as a future
optimization.

disk: Add an option for partitions in SPL

2022-03-25T20:42:40+00:00

In some cases we do not want to enable partition support in SPL. Add an
option to allow this.
