spi: rk: Limit transfers to (64K - 1) bytes

The Rockchip SPI controller's length register only supports 16-bits,
yielding a maximum length of 64KiB (the CTRLR1 register holds "length -
1"). Trying to transfer more than that (e.g., with a large SPI flash
read) will cause the driver to hang.

Now, it seems that while theoretically we should be able to program
CTRLR1 with 0xffff, and get a 64KiB transfer, but that also seems to
cause the core to choke, so stick with a maximum of 64K - 1 bytes --
i.e., 0xffff.

Note, that the size is further divided into 'minus 1' while writing
into CTRLR1.

This change fixed two different read issues,

1. sf read failure when with > 0x10000

2. Boot from SPI flash failed during spi_flash_read call in

i2c: i2c_cdns: fix write timeout on fifo boundary

This fixes an issue that would cause I2C writes to timeout when the
number of bytes is a multiple of the FIFO depth (i.e. 16 bytes).

Within the transfer loop, after writing the data register with a new
byte to transfer, if the transfer size equals the FIFO depth, the loop
pauses until the INTERRUPT_COMP bit asserts to indicate data has been
sent. This same check is performed after the loop as well to ensure data
has been transferred prior to returning.

In the case where the amount of data to be written is a multiple of the
FIFO depth, the transfer loop would wait for the INTERRUPT_COMP bit to
assert after writing the final byte, and then wait for this bit to
assert once more. However, since the transfer has finished at this
point, no new data has been written to the data register, and hence
INTERRUPT_COMP will never assert.

Fix this by only waiting for INTERRUPT_COMP in the transfer loop if
there's still data to be written.

Lukas Auer [Sun, 8 Dec 2019 22:28:49 +0000 (23:28 +0100)]
spl: opensbi: specify main hart as preferred boot hart

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").

riscv: increase stack size to avoid a stack overflow during distro boot

This fixes a problem, where booting Linux using distro boot will
sometimes lead to an invalid instruction exception on the main hart. The
secondary harts are not affected and boot Linux successfully. The root
cause of this problem is a stack overflow on the main hart.

With distro boot, the current default stack size of 8KiB on RISC-V is
not sufficient and will cause a stack overflow. The stacks are allocated
sequentially. In the case of a stack overflow the stack of the main hart
can reach into that of another hart and be corrupted.

The stack overflow previously did not cause any problems, because only
stack frames, which are not used anymore since the hart enters Linux,
were corrupted. Starting with GCC 9, the stack usage has decreased. Now,
only the most recent stack frame overflows into the stack of a secondary
hart and is corrupted. The illegal instruction exception is caused by
the secondary hart overwriting the return address in the stack frame of
the main hart with an address that does not include valid code.

Increase the default stack size of each hart to 16KiB to avoid this
problem.

4 years agonet: tftp: Fix too small block size
Andre Przywara [Sat, 23 Nov 2019 17:58:59 +0000 (17:58 +0000)]
net: tftp: Fix too small block size

Commit b618b3707633 ("net: Convert CONFIG_TFTP_BLOCKSIZE to Kconfig")
accidentally set the default *option* TFTP block size to 512 bytes, even
though the comment in the code says that this is a terrible choice. Most
boards didn't define the symbol before, so they got the default block size
of 1468 bytes before, but now use 512 bytes, which is also the fallback.
This leads to both abysmal performance and a lot of hashes printed
on the screen (one character for every 5K), which is both annoying and
slow over serial links.

Set the default block size in Kconfig back to the value it had before.

This improves TFTP performance from 2.8 MB/s to 6.9 MB/s on a Pine64.
