4 years agodm: Support parent devices with of-platdata

dm: Support parent devices with of-platdata

At present of-platdata does not provide parent information. But this is
useful for I2C devices, for example, since it allows them to determine
which bus they are on.

Add support for setting the parent correctly, by storing the parent
driver_info index in dtoc and reading this in lists_bind_drivers(). This
needs multiple passes since we must process children after their parents
already have been bound.

This command lets the user list, select, and deselect mux controllers

list, select, and deselect.

List: Lists all the mux present on the system. The muxes are listed for
each chip. The chip is identified by its device name. Each chip can have
a number of mux controllers. Each is listed in sequence and is assigned
a sequential ID based on its position in the mux chip. It lists details
like ID, whether the mux is currently selected or not, the current
state, the idle state, and the number of states.

A sample output would look something like:

=> mux list
a-mux-controller:
ID Selected Current State Idle State Num States
0 no         unknown    as-is      0x4
1 no         0x2        0x2        0x10

        0       no              0x1             0x1             0x4
        1       no              0x2             0x2             0x4

Select: Selects a given mux and puts it in the specified state. This
subcommand takes 3 arguments: mux chip, mux ID, state to set
the mux in. The arguments mux chip and mux ID are used to identify which
mux needs to be selected, and then it is selected to the given state.
The mux needs to be deselected before it can be selected again in
another state. The state should be a hexadecimal number.

For example:
=> mux list

        0       no              0x1             0x1             0x4

U-Boot Driver Model is supposed to remove devices with either
DM_REMOVE_ACTIVE_DMA or DM_REMOVE_OS_PREPARE flags set, before exiting.
Our bootm command does that by explicitly calling calling
"dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL);" and we also disable any
USB devices.

The EFI equivalent is doing none of those at the moment. As a result
probing an fTPM driver now renders it unusable in Linux. During our

close with our (*remove) callback. Since the (*remove) is never called,
once we boot into Linux and try to probe the device again we are getting
a busy error response. Moreover all uclass (*preremove) functions won't
run.

bootm: fix wrong conditions about images overlap

It doesn't need to consider start byte address.
If ramdisk size is 0x800000 and start address is 0x2700000, then it's
used until 0x02efffff, not 0x02f00000. But it's detected to overlapt RD
image, when kernel start address is 0x02f00000.
Because it's doing wrong calculation about rd_len.
This patch fixed wrong calculation address position when check
condition.

In addition, it needs to check one more condition about overlapping
entire area.

Pali Rohár [Wed, 7 Oct 2020 13:39:40 +0000 (15:39 +0200)]
Makefile: Fix u-boot-nodtb.bin target

This change fixes two issues when building u-boot-nodtb.bin target:

* Remove intermediate binary u-boot-nodtb.bin from disk when static_rela
  call (which modifies u-boot-nodtb.bin binary) failed. It is required
  because previous objcopy call creates binary and static_rela finish it.

* Do not call static_rela cmd when u-boot-nodtb.bin binary was not
  created/updated by previous objcopy call.

Second fix would ensure that u-boot-nodtb.bin binary is not updated when
all prerequisites were up-to-date. And therefore final binary u-boot.bin
is not updated in case all prerequisites were not modified and were
up-to-date.

Now running 'make SOURCE_DATE_EPOCH=0 u-boot.bin' second time now does not
touch u-boot.bin binary in case nothing was modified, so GNU make can
correctly detect that everything is up-to-date.
