Dynamic SAR allows changing TX power limits at runtime to comply with SAR regulations on multiple form factors (e.g. tablet vs. clamshell mode). To support this, a new table was added to ACPI, which is called Extended Wireless Regulatory Descriptor (EWRD). This table allows OEMs to define different TX power profiles for each form-factor or usage mode. Read this new table and store it in our SAR profiles table, in preparation for Dynamic SAR support.

We are adding support for dynamic TX power tables for SAR (specific absorption rate) compliance. Currently, we only support a single (static) TX power table, which is read from ACPI, and use it statically. To prepare for more tables that can be switched dynamically, refactor the SAR init flow to allow reusage and add the current static table as a single entry in an array of tables.

In a000 devices we will support up to 32 stations. The max station define is used also for invalid station marking which makes finding usages of actual maximum station pretty hard to sort through - change it to be a different define in order to make future changes easier. Use also ARRAY_SIZE intead of define when possible. Do not move yet to 32 stations until firmware do it though.

When driver needs to access the contents of a streaming DMA buffer without unmapping it it should call dma_sync_single_for_cpu(). Once the call has been made, the CPU "owns" the DMA buffer and can work with it as needed. Before the device accesses the buffer, however, ownership should be transferred back to it with dma_sync_single_for_device(). Both calls weren't performed by the driver, resulting with odd paging errors on some platforms. Fix it.

For a000 devices the INIT and RT images are unified to one image. The changes in the flow are the following: * Driver load only RT firmware - meaning that the nvm access command will be done in the RT image load flow. * A new command (NVM_ACCESS_COMPLETE) now signals to the FW that the driver is done accessing the NVM and FW can proceed with phy calibrations. * Phy DB is no longer sent from INIT FW to be restored by driver for the RT FW - all the phy DB is now internal to the FW. INIT complete will now follow the NVM access command, without phy DB calls before. * Paging command is sent earlier in the flow before NVM access to enable a complete load of FW. * caution must be care when restart is called since we may have not completed init flow even though we are in RT firmware.

The firwmare file can come with data that is relevant for paging. This data is availablet to the firmware upon request, but it stored in the host's memory. During the firmware init flow, the driver configures the firmware so that the firwmare knows where is the data. When paging is used, the variable paging_mem_size is the number of bytes that are available through paging. This variable is not zeror-ed if the driver fails to configure the paging in the firmware, but the memory is freed which is inconsistent. This inconsistency led to a NULL pointer dereference in the code that collects the debug data. Fix this by zero-ing the paging_mem_size variable and NULLify the relevant pointers, so that the code that collects the debug data will know that the paging data is not available.

Paging contains 3 sections in the fw. The first for the paging separator, The second for the CSS block, the third with the paging data. Currently if the driver finds the paging separator, and there is only section left (CSS), once reading the CSS section, the driver will attempt to read the paging data and will go out of the arrays bounds. Make sure that the FW image contains the right amount of sections for paging. Signed-off-by: NMatti Gottlieb <matti.gottlieb@intel.com> Signed-off-by: NEmmanuel Grumbach <emmanuel.grumbach@intel.com>

Currently the driver has 2 buffers for paging: 1. paging db - this contains all of the pages that were in the FW image, that the driver stores for the FW. This is allocated for each block separately (not contiguous). 2. download buffer - we need to provide this empty buffer for the iwl_sdio_load_fw_chunk function to copy the requested pages to the shared memory. This is one big buffer of contiguous memory whose size is the size of all the blocks that the fw paging section can contain. This download buffer size is too big, and causes the allocation to fail sometimes. Since the driver allocates memory for each block separately, it is not possible for the FW to request all of the pages in one request (the FW gives an address and size, so blocks need to be contiguous for this to happen), therefore the FW is limited to request only one block. Decrease the size of the paging download buffer to be the size of a paging block.
