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.

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.

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.
