sunxi: define SYS_MONITOR_LEN in Kconfig, not _defconfig

2022-12-13T20:33:31+00:00

Commit 08574ed339fb ("Convert CONFIG_SYS_MONITOR_LEN to Kconfig") moved
the definition of said config variable from the common sunxi header to
*every board's* defconfig.
This is a platform choice, not board specific, so remove the variable
from there, instead set the one value for all Allwinner boards in
Kconfig.

Convert CONFIG_SYS_MONITOR_LEN to Kconfig

2022-11-10T15:08:55+00:00

This converts the following to Kconfig:
   CONFIG_SYS_MONITOR_LEN

To do this, we set a default of 0 for everyone because there are a
number of cases where we define CONFIG_SYS_MONITOR_LEN but the only
impact is that we set TOTAL_MALLOC_LEN to be CONFIG_SYS_MALLOC_LEN +
CONFIG_ENV_SIZE, so we must continue to allow all boards to set this
value. Update the SPL code to use 200 KB as the default raw U-Boot size
directly, if we don't have a real CONFIG_SYS_MONITOR_LEN value.

Makefile: Rename u-boot-spl.kwb to u-boot-with-spl.kwb

2022-11-07T06:17:55+00:00

File name with pattern u-boot-spl* is used on all places except in kwb
image for binary with SPL-only code. Combined binary with both SPL and
proper U-Boot in other places has file name pattern u-boot-with-spl*.

Make it consistent also for kwb image and rename u-boot-spl.kwb to
u-boot-with-spl.kwb as this image contains both SPL and proper U-Boot code.

Also update documentation about file name changes.

Rename CONFIG_SYS_TEXT_BASE to CONFIG_TEXT_BASE

2022-10-31T15:01:31+00:00

The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE
and this makes it imposible to use CONFIG_VAL().

Rename it to resolve this problem.

sunxi: Kconfig: introduce SUNXI_MINIMUM_DRAM_MB

2022-10-19T13:15:02+00:00

Traditionally we assumed that every Allwinner board would come with at
least 256 MB of DRAM, and set our DRAM layout accordingly. This affected
both the default load addresses, but also U-Boot's own address
expectations (like being loaded at 160 MB).

Some SoCs come with co-packaged DRAM, but only provide 32 or 64MB. So
far we special-cased those *chips*, as there was only one chip per DRAM
size. However new chips force us to take a more general approach.

Introduce a Kconfig symbol, which provides the minimum DRAM size of the
board. If nothing else is specified, we use 256 MB, and default to
smaller values for those co-packaged SoCs.
Then select the different DRAM maps according to this new symbol, so
that different SoCs with the same DRAM size can share those definitions.

Inspired by an idea from Icenowy.

This is just refactoring: compiled for all boards before and after this
patch: the binaries were identical.

arm64: versal-net: Add support for Versal NET platform

2022-09-26T12:23:29+00:00

Versal NET platform is based on Versal chip which is reusing a lot of IPs.
For more information about new IPs please take a look at DT which describe
currently supported devices.
The patch is adding architecture and board support with soc detection
algorithm. Generic setting should be very similar to Versal but it will
likely diverge in longer run.

Kconfig: enlarge CONFIG_SYS_MALLOC_F_LEN

2022-09-18T20:56:10+00:00

"alloc space exhausted" happens in very early stage, which could be seen
with DEBUG_UART options enabled and leeds to an non-functional board.

kontron_pitx_imx8m:
CONFIG_DEBUG_UART_BASE=0x30880000   # for serial3
CONFIG_DEBUG_UART_CLOCK=24000000

imx8mqevk:
CONFIG_DEBUG_UART_BASE=0x30860000      # for uart1
CONFIG_DEBUG_UART_CLOCK=24000000

It is because CONFIG_SYS_MALLOC_F_LEN is too small and still leave
CONFIG_SPL_SYS_MALLOC_F_LEN as 0x2000.

sandbox: Add support for Address Sanitizer

2022-06-23T16:58:18+00:00

Add CONFIG_ASAN to build with the Address Sanitizer. This only works
with the sandbox so the config is likewise dependent. The resulting
executable will have ASAN instrumentation, including the leak detector
that can be disabled with the ASAN_OPTIONS environment variable:

   ASAN_OPTIONS=detect_leaks=0 ./u-boot

Since u-boot uses its own dlmalloc, dynamic allocations aren't
automatically instrumented, but stack variables and globals are.

Instrumentation could be added to dlmalloc to poison and unpoison memory
as it is allocated and deallocated, and to introduce redzones between
allocations. Alternatively, the sandbox may be able to play games with
the system allocator and somehow still keep the required memory
abstraction. No effort to address dynamic allocation is made by this
patch.

The config is not yet enabled for any targets by default.

Migrate CUSTOM_SYS_INIT_SP_ADDR to Kconfig using system-constants.h

2022-06-06T16:09:19+00:00

- Make all users of CUSTOM_SYS_INIT_SP_ADDR reference SYS_INIT_SP_ADDR
- Introduce HAS_CUSTOM_SYS_INIT_SP_ADDR to allow for setting the stack
  pointer directly, otherwise we use the common calculation.
- On some platforms that were using the standard calculation but did not
  set CONFIG_SYS_INIT_RAM_SIZE / CONFIG_SYS_INIT_RAM_ADDR, set them.
- On a small number of platforms that were not subtracting
  GENERATED_GBL_DATA_SIZE do so now via the standard calculation.
- CONFIG_SYS_INIT_SP_OFFSET is now widely unused, so remove it from most
  board config header files.
