4 years agoriscv: Fix breakage caused by linker relaxation
Sean Anderson [Wed, 18 Dec 2019 02:35:32 +0000 (21:35 -0500)]
riscv: Fix breakage caused by linker relaxation

Due to the two-instruction sequence needed to access arbitrary memory
locations, the RISC-V linker aggressively optimises memory accesses and
jumps at link-time. This is called "linker relaxation," and is discussed
in this SiFive article
<https://www.sifive.com/blog/all-aboard-part-3-linker-relaxation-in-riscv-toolchain>.
One of the optimizations in place is to assume that the __global_pointer
symbol is placed in the gp register. To quote the article:

"...The magic __global_pointer$ symbol is defined to point 0x800 bytes
past the start of the .sdata section. The 0x800 magic number allows
signed 12-bit offsets from __global_pointer$ to address symbols at the
start of the .sdata section. The linker assumes that if this symbol is
defined, then the gp register contains that value, which it can then use
to relax accesses to global symbols within that 12-bit range. The
compiler treats the gp register as a constant so it doesn't need to be
saved or restored, which means it is generally only written by _start,
the ELF entry point."

However, U-Boot instead keeps the global data pointer in gp. This causes
memory accesses and jumps optimized to use the gp pointer to fail. To
fix this problem, we undefine the __global_pointer symbol.

The watchdog timer value was never updated in the hardware by this

was left in the hardware. The TI SPRUH37C says, quote:

  20.4.3.9 Modifying Timer Count/Load Values and Prescaler Setting
  ...
  After a write access, the load register value and prescaler ratio
  registers are updated immediately, but new values are considered
  only after the next consecutive counter overflow or after a new
  trigger command (the WDT_WTGR register).

This means at least one trigger must happen. The driver probably
depended on someone calling it's .reset() callback, however that
is not guaranteed e.g. if the WDT operates without servicing.

4 years agoimage: android: Add functions for handling dtb field
Sam Protsenko [Fri, 24 Jan 2020 15:53:40 +0000 (17:53 +0200)]
image: android: Add functions for handling dtb field

Android Boot Image v2 adds "DTB" payload (and corresponding field in the
image header). Provide functions for its handling:

  - android_image_get_dtb_by_index(): Obtain DTB blob from "DTB" part of
    boot image, by blob's index
  - android_image_print_dtb_contents(): Iterate over all DTB blobs in
    "DTB" part of boot image and print those blobs info

"DTB" payload might be in one of the following formats:
  1. concatenated DTB blobs
  2. Android DTBO format

The latter requires "android-image-dt.c" functionality, so this commit
selects that file for building for CONFIG_ANDROID_BOOT_IMAGE option.

Right now this new functionality isn't used, but it can be used further.
As it's required to apply some specific dtbo blob(s) from "dtbo"
partition, we can't automate this process inside of "bootm" command. But
we can do next:
  - come up with some new command like "abootimg" to extract dtb blob
    from boot image (using functions from this patch)
  - extract desired dtbo blobs from "dtbo" partition using "adtimg"
    command
  - merge dtbo blobs into dtb blob using "fdt apply" command
  - pass resulting dtb blob into bootm command in order to boot the
    Android kernel with Android ramdisk from boot image

spi: ich: Drop while loop in hardware sequencing erase case

When ich_spi_exec_op_hwseq() is called to erase a 4k block
(opcode = SPINOR_OP_BE_4K), it expects to find a length value in
op->data.nbytes, but that value is always 0. As a result, the while loop
is never executed and no erase is carried out.

Fix this by dropping the loop code entirely, only keeping the relevant
parts of the loop body.
