The implementation of FW_LOADER requires CMDLINE to be enabled, and expressses this. In order to not have to have every users also depends on CMDLINE introduce SUPPORTS_FW_LOADER. This depends on CMDLINE and ENV_SUPPORT and then we have all users depends on SUPPORTS_FW_LOADER. Signed-off-by: Tom Rini <trini@konsulko.com>
The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c8c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).
This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

Aquantia PHYs are being used w/o SPI flash in some routers recently. Current firmware loader only attempts to load from FS on top of MMC, limiting the use on many devices. Removed the old firmware loader, migrate to generic script based firmware loader to allow a wider range and runtime override of firmware source. (e.g., MMC, USB, UBIFS). Tested on Buffalo WXR18000BE10P with UBIFS. Signed-off-by: Beiyan Yun <root@infi.wang>
These two PHY drivers have some overlap of supported PHYs. A longer term effort is needed to both remove duplication and enhance support by dealing with some issues that downstream vendor drivers address. For now, make both of these depend on !COMPILE_TEST so that we can enable "allyesconfig". Signed-off-by: Tom Rini <trini@konsulko.com>
Add the driver for the Airoha EN8811H 2.5 Gigabit PHY. The PHY supports 100/1000/2500 Mbps with auto negotiation only. The driver uses two firmware files, for which updated versions are added to linux-firmware already. Locating the AIROHA FW within the filesystem at the designated partition and path will trigger its automatic loading and writing to the PHY via MDIO. If need board specific loading override, please override the en8811h_read_fw function on board or architecture level. Based on the Linux upstream AIROHA EN8811H driver code(air_en8811h.c), I have modified the relevant process to align with the U-Boot boot sequence. and have validated this on Banana Pi BPI-R3 Mini.

With commit 597fe041a85f ("net/phy: enable get_phy_id redefinable") we
made get_phy_id a public but weak function, so that PHY drivers that had
required non-standard ways of getting the PHY ID could be supported.
However, overloading a weak function multiple times is (rightly) a link
error. At this point, we have two PHYs which make use of this feature,
so make both of them only available when COMPILE_TEST is unset, as part
of being able to support "allyesconfig" in the future.

The MediaTek MT7987/MT7988 SoCs features a built-in 2.5Gb PHY
connected to GMAC1. The PHY supports 10/100/1000/2500 Mbps
full-duplex only.
The PHY requires one or two firmware files. Firmware for MT7988 has
already been added to upstream: mediatek/mt7988/i2p5ge-phy-pmb.bin.
MT7987 has two firmware files which will be add to upstream later:
i2p5ge-phy-pmb.bin and i2p5ge-phy-DSPBitTb.bin.
Environment variable can be set for firmware data loading:
mt7987_i2p5ge_load_pmb_firmware for i2p5ge-phy-pmb.bin
mt7987_i2p5ge_load_dspbit_firmware for i2p5ge-phy-DSPBitTb.bin
mt7988_i2p5ge_load_pmb_firmware for i2p5ge-phy-pmb.bin
This driver allows dedicated weak functions to be overridden by
board to provide the firmware data:
mt7987_i2p5ge_get_fw() for MT7987
mt7988_i2p5ge_get_fw() for MT7988
To enable the PHY, add the following not to device tree:
ð1 {
status = "okay";
phy-mode = "xgmii";
phy-handle = <&phy15>;
phy15: ethernet-phy@15 {
compatible = "ethernet-phy-ieee802.3-c45";
reg = <15>;
phy-mode = "xgmii";
};
};

The Auto Negotiation procedure between two Ethernet PHYs consists of determining the best commonly supported parameters among Speed, Duplex Mode and Flow Control. The time taken for this procedure is not only dependent on the local PHY used, but also on the link-partner PHY. While a timeout can be specified in the form of a "CONFIG" on the basis of the local PHY present on the device, since the timeout also depends on the link-partner PHY, it might be necessary to modify the timeout. To avoid rebuilding the bootloader for a given device, just because it may be connected to various link-partner PHYs, each with a different timeout, introduce an environment variable named "phy_aneg_timeout" and override "CONFIG_PHY_ANEG_TIMEOUT" with "phy_aneg_timeout".

The DP83867 PHY driver is used by the BeagleBoneGreen Eco board, but adding it to the am335x-evm defconfig causes SPL to overflow its size limits. Add a separate option to enable this driver in SPL, so that it can be enabled in U-Boot without adding unnecessary volume to SPL.
