2017-03-29net: mvpp2: add and use accessors for TX/RX descriptorsThomas Petazzoni
The PPv2.2 IP has a different TX and RX descriptor layout compared to PPv2.1. In order to prepare for the introduction of PPv2.2 support in mvpp2, this commit adds accessors for the different fields of the TX and RX descriptors, and changes the code to use them. For now, the mvpp2_port argument passed to the accessors is not used, but it will be used in follow-up to update the descriptor according to the version of the IP being used. Apart from the mechanical changes to use the newly introduced accessors, a few other changes, needed to use the accessors, are made: - The mvpp2_txq_inc_put() function now takes a mvpp2_port as first argument, as it is needed to use the accessors. - Similarly, the mvpp2_bm_cookie_build() gains a mvpp2_port first argument, for the same reason. - In mvpp2_rx_error(), instead of accessing the RX descriptor in each case of the switch, we introduce a local variable to store the packet size. - Similarly, in mvpp2_buff_hdr_rx(), we introduce a local "cookie" variable to store the RX descriptor cookie, rather than accessing it from the descriptor each time. - In mvpp2_tx_frag_process() and mvpp2_tx() instead of accessing the packet size from the TX descriptor, we use the actual value available in the function, which is used to set the TX descriptor packet size a few lines before.

2017-03-29net: mvpp2: use "dma" instead of "phys" where appropriateThomas Petazzoni
As indicated by Russell King, the mvpp2 driver currently uses a lot "phys" or "phys_addr" to store what really is a DMA address. This commit clarifies this by using "dma" or "dma_addr" where appropriate. This is especially important as we are going to introduce more changes where the distinction between physical address and DMA address will be key.

2017-03-29net: mvpp2: enable building on 64-bit platformsThomas Petazzoni
The mvpp2 is going to be extended to support the Marvell Armada 7K/8K platform, which is ARM64. As a preparation to this work, this commit enables building the mvpp2 driver on ARM64, by: - Adjusting the Kconfig dependency - Fixing the types used in the driver so that they are 32/64-bits compliant. We use dma_addr_t for DMA addresses, and unsigned long for virtual addresses. It is worth mentioning that after this commit, the driver is for now still only used on 32-bits platforms, and will only work on 32-bits platforms. Changed by Stefan for U-Boot: Removed the Kconfig change as it does not apply to U-Boot this way.

2017-03-29net: mvpp2: simplify MVPP2_PRS_RI_* definitionsThomas Petazzoni
Some of the MVPP2_PRS_RI_* definitions use the ~(value) syntax, which doesn't compile nicely on 64-bit. Moreover, those definitions are in fact unneeded, since they are always used in combination with a bit mask that ensures only the appropriate bits are modified. Therefore, such definitions should just be set to 0x0. In addition, as suggested by Russell King, we change the _MASK definitions to also use the BIT() macro so that it is clear they are related to the values defined afterwards. For example: #define MVPP2_PRS_RI_L2_CAST_MASK 0x600 #define MVPP2_PRS_RI_L2_UCAST ~(BIT(9) | BIT(10)) #define MVPP2_PRS_RI_L2_MCAST BIT(9) #define MVPP2_PRS_RI_L2_BCAST BIT(10) becomes #define MVPP2_PRS_RI_L2_CAST_MASK (BIT(9) | BIT(10)) #define MVPP2_PRS_RI_L2_UCAST 0x0 #define MVPP2_PRS_RI_L2_MCAST BIT(9) #define MVPP2_PRS_RI_L2_BCAST BIT(10) Because the values (MVPP2_PRS_RI_L2_UCAST, MVPP2_PRS_RI_L2_MCAST and MVPP2_PRS_RI_L2_BCAST) are always applied with MVPP2_PRS_RI_L2_CAST_MASK, and therefore there is no need for MVPP2_PRS_RI_L2_UCAST to be defined as ~(BIT(9) | BIT(10)). It fixes the following warnings when building the driver on a 64-bit platform (which is not possible as of this commit, but will be enabled in a follow-up commit): drivers/net/ethernet/marvell/mvpp2.c: In function ‘mvpp2_prs_mac_promisc_set’: drivers/net/ethernet/marvell/mvpp2.c:524:33: warning: large integer implicitly truncated to unsigned type [-Woverflow] #define MVPP2_PRS_RI_L2_UCAST ~(BIT(9) | BIT(10)) ^ drivers/net/ethernet/marvell/mvpp2.c:1459:33: note: in expansion of macro ‘MVPP2_PRS_RI_L2_UCAST’ mvpp2_prs_sram_ri_update(&pe, MVPP2_PRS_RI_L2_UCAST, Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Stefan Roese <sr@denx.de> Acked-by: Joe Hershberger <joe.hershberger@ni.com>

The mvpp2_bm_bufs_add() currently creates a fake cookie by calling mvpp2_bm_cookie_pool_set(), just to be able to call mvpp2_pool_refill(). But all what mvpp2_pool_refill() does is extract the pool ID from the cookie, and call mvpp2_bm_pool_put() with this ID.

If we want to load a key into a TPM, we need to know the designated parent key's handle, so that the TPM is able to insert the key at the correct place in the key hierarchy. However, if we want to load a key whose designated parent key we also previously loaded ourselves, we first need to memorize this parent key's handle (since the handles for the key are chosen at random when they are inserted into the TPM). If we are, however, unable to do so, for example if the parent key is loaded into the TPM during production, and its child key during the actual boot, we must find a different mechanism to identify the parent key. To solve this problem, we add a function that allows U-Boot to load a key into the TPM using their designated parent key's SHA1 hash, and the corresponding auth data.

2017-03-26drivers/net/phy: add fixed-phy / fixed-link supportHannes Schmelzer
This patch adds support for having a "fixed-link" to some other MAC (like some embedded switch-device). For this purpose we introduce a new phy-driver, called "Fixed PHY". Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is described with a subnode below ethernet interface. Most ethernet drivers (unfortunately not all are following same scheme for searching/attaching phys) are calling "phy_connect(...)" for getting a phy-device. At this point we link in, we search here for a subnode called "fixed- link", once found we start phy_device_create(...) with the special phy- id PHY_FIXED_ID (0xa5a55a5a). During init the "Fixed PHY" driver has registered with this id and now gets probed, during probe we get all the details about fixed-link out of dts, later on the phy reports this values.
