From fd6b40b1ba20b7344e85c0c97eb1c4d14ed72a98 Mon Sep 17 00:00:00 2001 From: Grygorii Strashko Date: Tue, 5 Feb 2019 17:31:21 +0530 Subject: [PATCH 01/46] firmware: ti_sci: Add support for NAVSS resource management Texas Instruments' System Control Interface (TI-SCI) Message Protocol abstracts management of NAVSS resources, like PSI-L pairing and unpairing, UDMAP tx/rx/flow configuration and Rings. This patch adds support for requesting and configuring such resources from TI-SCI firmware.

There is one RINGACC module per NAVSS on TI AM65x SoCs. The RINGACC converts constant-address read and write accesses to equivalent read or write accesses to a circular data structure in memory. The RINGACC eliminates the need for each DMA controller which needs to access ring elements from having to know the current state of the ring (base address, current offset). The DMA controller performs a read or write access to a specific address range (which maps to the source interface on the RINGACC) and the RINGACC replaces the address for the transaction with a new address which corresponds to the head or tail element of the ring (head for reads, tail for writes). Since the RINGACC maintains the state, multiple DMA controllers or channels are allowed to coherently share the same rings as applicable. The RINGACC is able to place data which is destined towards software into cached memory directly. Supported ring modes: - Ring Mode - Messaging Mode - Credentials Mode - Queue Manager Mode TI-SCI integration: Texas Instrument's System Control Interface (TI-SCI) Message Protocol now has control over Ringacc module resources management (RM) and Rings configuration. The Ringacc driver manages Rings allocation by itself now and requests TI-SCI firmware to allocate and configure specific Rings only. It's done this way because, Linux driver implements two stage Rings allocation and configuration (allocate ring and configure ring) while TI-SCI Message Protocol supports only one combined operation (allocate+configure).

The UDMA-P module supports the transmission and reception of various packet types. The UDMA-P also supports acting as both a UTC and UDMA-C for its internal channels. Channels in the UDMA-P can be configured to be either Packet-Based or Third-Party channels on a channel by channel basis. The initial driver supports: - MEM_TO_MEM (TR mode) - DEV_TO_MEM (Packet mode) - MEM_TO_DEV (Packet mode) Signed-off-by: Peter Ujfalusi Signed-off-by: Grygorii Strashko Signed-off-by: Vignesh R ---

EVM hardware spec recommends to add 0.25 nsec delay in the tx direction and 2.25 nsec delay in the rx direction for internal delay in the clock path to be on the safer side. The board straps RX_DV/RX_CTRL pin of on board DP83867 phy in mode 1. Unfortunately, the phy data manual disallows this. Add ti,dp83867-rxctrl-strap-quirk in the phy node to allow software to enable workaround suggested for this incorrect strap setting. This ensures proper operation of this PHY. The dts bindings are kept in sync with that from 4.14.y linux kernel. This required the pinmux device related bindings to be commented out to allow for compilation.

To enable CONFIG_SPL_ETH_SUPPORT, we must enable CONFIG_SPL_ENV_SUPPORT as the environment is used by the eth support, but we don't actually need to have environment variables saved in the SPL environment. We do however have environment variables saved in the main U-Boot image and enable CONFIG_ENV_OFFSET_REDUND (we are storing in raw NAND). In such instances, even with the build config enabling both CONFIG_CMD_SAVEENV and CONFIG_CMD_NAND, these options aren't set when building the SPL, but CONFIG_ENV_OFFSET_REDUND still is. Don't check this configuration option for SPL builds to enable the above configuration.

This patch relocates BSS to SDRAM instead of SRAM which is similar to how ARMv7 boards (like OMAP2+) do it. This means two new variables are required: CONFIG_SPL_BSS_START_ADDR set to DAVINCI_DDR_EMIF_DATA_BASE CONFIG_SPL_BSS_MAX_SIZE is set to 0x1080000 which is 1 byte before the location where U-Boot will load.

Therefore, create a seperate entry that can be use to reconfigure these pins to work for NAND. On the EVM SWITCH 8 pins 0 and 1 will be used to determine if NAND is enabled or not. For NAND to be selected pin 0 should be on and pin 1 should be off. Any other combination will assume NAND shouldn't be enabled.

Since the available size can vary, changing DT every time the size varies might be painful. So, query this information using TISCI cmd and fixup the DT for kernel. Fixing up DT does the following: - Create a sram node if not available - update the reg property with available size - update ranges property - loop through available sub nodes and delete it if: - mentioned size is out if available range - subnode represents l3 cache or dmsc usage.

Divide these two steps into separate functions one of which can be called from ofdata_to_platdata() while the other can be called from _probe(). This ensures that platdata can be assigned statically in a board file when OF_CONTROL is not enabled. Also add a macid_sel_compat in private data to get information about the macid byte placement.
