Marek Bykowski [Wed, 29 Apr 2020 16:23:07 +0000 (18:23 +0200)]
malloc: dlmalloc: add an ability for the malloc to be re-init/init multiple times

Malloc gets initialized with a call to mem_malloc_init() with the address
the allocation starts to and its size. Currently it is not possible to
move the malloc from one memory area to another as the malloc would eventually
fail.

This patch adds in the ability to re-init the malloc with the updated
start address and the size.

One of the use cases of this feature is SPL U-Boot running from within
the static memory and calling to malloc init from within board_init_f():

arch/arm/cpu/armv8/start.S:reset vector
arch/arm/cpu/armv8/start.S:main()
arch/arm/lib/crt0_64.S:board_init_f()
board/<my_board>/common/spl.c:board_init_f()
        board/<my_board>/common/spl.c:mem_malloc_init((ulong)CONFIG_SYS_SPL_MALLOC_START,
                        CONFIG_SYS_SPL_MALLOC_SIZE);

Shortly after the DDR (main) memory is init and ready we call to malloc init
again but this time with the start address in the DDR memory and a much greater
size for moving the allocation off the static to the DDR memory:

board/<my_board>/common/spl.c:mem_malloc_init((ulong)CONFIG_SPL_MALLOC_OFFSET,
CONFIG_SPL_MALLOC_SIZE);

Where CONFIG_SYS_SPL_MALLOC_START and CONFIG_SPL_MALLOC_OFFSET are the start
addresses of the malloc in the static and DDR memories respectively and
CONFIG_SYS_SPL_MALLOC_SIZE=SZ_16K and CONFIG_SPL_MALLOC_SIZE=SZ_2M are
the sizes of the mallocs in these memories. Note, now we have a much greater
memory, enlarging from 16K to 2M, available for allocation.

There is an alternative approach already existing in U-Boot with the use of
an early (simplified) malloc and the proper (dlamalloc) malloc however
necessitating managing the two mallocs whereas this approach proposes using
a single dlmalloc.

The ROC-RK3328-CC from Firefly and Libre Computer Project is a credit
card size development board based on the Rockchip RK3328 SoC, with:

  - 1/2/4 GB DDR4 DRAM
  - eMMC connector for optional module
  - micro SD card slot
  - 1 x USB 3.0 host port

  - HDMI video output
  - TRRS connector with audio and composite video output
  - gigabit Ethernet
  - consumer IR receiver
  - debug UART pins

The ROC-RK3328-CC has the enable pin of the SD card power switch tied
to GPIO_0_D6. This pin also has the function SDMMC0_PWREN, which is
muxed by default. SDMMC0_PWREN is an active high signal controlled by
the MMC controller, however the switch enable is active low, and
pulled low (enabled) by default to make things work on boot.

As such, we need to mux away from SDMMC0_PWREN and use GPIO to enable
power to the card. The default GPIO state for the pin is pull-down and
input, which doesn't require extra configuration when paired with the
external pull-down and active low switch.

Deal with this by enabling regulator support in SPL, and setting
"u-boot,dm-spl" for the regulator and other device nodes needed for
muxing the pin.

patch and tested via SPI-NOR and MMC_SPI.
   
- set the frame format proto, endian
- set the frame format dir, set it for tx and clear it for rx
- TX transfer:
  fill tx fifo with data.
  wait for TX watermark bit to clear.
- RX transfer:
  fill tx fifo with 0xff.
  write nbytes to rx watermark register
  wait for rx watermark bit to clear.
  read the rx fifo data.

So, this patch adopts this program sequence and fixes the existing
I/O direction bit.

spi: sifive: Fix format register proto field

SiFive SPI controller has a proto bit field in frame format
register which would be used to configure the SPI I/O protocol
lines used on specific transfer. 

Right now the driver is configuring this proto using slave->mode,
for all types of transctions. This makes the driver unable to
function since the proto needs to configure dynamically for
each and every transaction separately at runtime.

Now, the controller driver supports per transfer via spi-mem
exec_opo, so add the fmt_proto flag and fill the per transfer
buswidth so that the controller configures the proto bit at
runtime.

This patch fixes the SPI controller works with SPI NOR flash
on quad read with page program.

4 years agospi: sifive: Add spi-mem exec op
Jagan Teki [Thu, 23 Apr 2020 17:00:53 +0000 (22:30 +0530)]
spi: sifive: Add spi-mem exec op

SiFive SPI controller is responsible to handle the
slave devices like mmc spi and spi nor flash.

The controller is designed such a way that it would
handle the slave transactions based on the I/O protocol
numbers, example if spi nor slave send quad write opcode
it has to send alone with I/O protocol number of 4 and
if it try to send data it has to send I/O protocol number
along with 4 line data.

But the current spi-xfer code from spi-mem is combining
the opcode and address in a single transaction, so the
SPI controller will be unable to identify the I/O protocol
number of opcode vs address.

So, add the spi-mem exec_op with spi-xfer of opcode, address
and data as a separate transaction. This doesn't remove
the .xfer of dm_spi_ops since mmc spi will make use of it.

Note: This code might have moved to the spi-mem core area
once we have done the dedicated tests on other controllers
and have real reason to move.
