Heinrich Schuchardt 56c9f0c44e efi_loader: CloseProtocol in efi_fmp_find
The CloseProtocol() boot service requires a handle as first argument.
Passing the protocol interface is incorrect.

CloseProtocol() only has an effect if called with a non-zero value for
agent_handle. HandleProtocol() uses an opaque agent_handle when invoking
OpenProtocol() (currently NULL). Therefore HandleProtocol() should be
avoided.

The following description is copied from the equivalent patch for the
Linux Kernel proposed by Aurelien Jarno:

>From version 2.38, binutils default to ISA spec version 20191213. This
means that the csr read/write (csrr*/csrw*) instructions and fence.i
instruction has separated from the `I` extension, become two standalone
extensions: Zicsr and Zifencei. As the kernel uses those instruction,
this causes the following build failure:

Ravi GunasekaranandTom Rini 9ea30ea66a net: ti: cpsw-mdio: Add workaround for errata i2329
In certain TI SoCs, on the CPSW and ICSS peripherals, there is
a possibility that the MDIO interface returns corrupt data on
MDIO reads or writes incorrect data on MDIO writes. There is also
a possibility for the MDIO interface to become unavailable until
the next peripheral reset.

The workaround is to configure the MDIO in manual mode and disable the
MDIO state machine and emulate the MDIO protocol by reading and writing
appropriate fields in MDIO_MANUAL_IF_REG register of the MDIO controller
to manipulate the MDIO clock and data pins.

More details about the errata i2329 and the workaround is available in:
https://www.ti.com/lit/er/sprz487a/sprz487a.pdf

Add implementation to disable MDIO state machine, configure MDIO in manual
mode and provide software MDIO read and writes via MDIO bitbanging. Allow
the MDIO to be initialized based on the need for manual mode.

Fix this issue by explicitly calling setup_all_pgtables() in dcache_enable()

In general handles should only be deleted if the last remaining protocol
is removed.  Instead of explicitly calling
efi_create_handle -> efi_add_protocol -> efi_delete_handle which blindly
removes all protocols from a handle before removing it,  use
InstallMultiple/UninstallMultiple which adheres to the EFI spec and only
deletes a handle if there are no additional protocols present

Ilias ApalodimasandHeinrich Schuchardt 05c4c9e21a efi_loader: define internal implementations of install/uninstallmultiple
A following patch is cleaning up the core EFI code trying to remove
sequences of efi_create_handle, efi_add_protocol.

Although this works fine there's a problem with the latter since it is
usually combined with efi_delete_handle() which blindly removes all
protocols on a handle and deletes the handle.  We should try to adhere to
the EFI spec which only deletes a handle if the last instance of a protocol
has been removed.  Another problem is that efi_delete_handle() never checks
for opened protocols,  but the EFI spec defines that the caller is
responsible for ensuring that there are no references to a protocol
interface that is going to be removed.

So let's fix this by replacing all callsites of
efi_create_handle(), efi_add_protocol() , efi_delete_handle() with
Install/UninstallMultipleProtocol.

In order to do that redefine functions that can be used by the U-Boot
proper internally and add '_ext' variants that will be used from the
EFI API

Heinrich Schuchardt 8f8fe1d458 efi_driver: add init function to EFI block driver
For handling added and removed block devices we need to register events
which has to be done when the driver is installed.

This patch only creates an empty init function that will be filled with
code later on. The function needs to be called before any EFI block devices
are used. Move the efi_driver_init() call to early init.

Heinrich Schuchardt ec4f675f9e efi_driver: provide driver binding protocol to bind function
DisconnectController() is based on the open protocol information created
when the driver opens a protocol with BY_CHILD_CONTROLLER or BY_DRIVER.

To create an open protocol information it is required to supply the handle
of the driver as agent handle. This information is available as field
DriverBindingHandle in the driver binding protocol.
