Looking for 125°C Automotive EPCS or EPCQ (replacement) version

Question

Dear Community and Intel/Altera,

i want to use your FPGAs in automotive designs (cyclone 5 and 10). I would like to use AS-Programming by a external flash chip.
I would like to use a small chip housing, if possible
Altera/Intel only offers ECPS, ECPQ, ECPS-A devices
EPCQ-A seems only suitable for 85°, is sthat correct? (https://www.altera.com/documentation/sli1498107252254.html)
EPCQ-L same problem: https://www.altera.com/documentation/wtw1396921531042.html#wtw1396921651224
EPCQ seems good for temperature https://www.altera.com/documentation/bhc1410934512298.htm (https://www.altera.com/documentation/bhc1410934512298.html)l but all chips below 265 kbit seems to be discontinued https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/pcn/pdn1708.pdf and larger chips only be stored for 10 years. It says there will be some support for other flash in Prime 17.1 - but this is not even released yet and i cannot check what chips will be the "alternatives"

So, finally, my question: Do you have a solution to connect your automotive 125°C FPGAs to a 125°C Flash Chip by AS-Programming? Is there an existing compatible alternative?

(The Device-ID-Check, which seems not able to be disabled during jtag-jic-file programming seems to kill all available alternatives (as Spansion is now Cypress), see https://www.altera.com/support/support-resources/knowledge-base/solutions/rd10252015_587.html)

Thank you very much!

Based on my understanding, the automotive range EPCQ devices are not not available. The recommended operating temperature range of EPCQ devices would be -40C to 85C.

Are you going to configure the FPGA at 125C by using the EPCQ device?

I think for FPGA &lt; gen10  it is easy to replace AS flash and then find other grades (and much lower prices).  EPCS replacement: http://fpgaforum.blogspot.de/2006/03/any-replacement-for-altera-epcs_19.html EPCQ replacement: http://fpgaforum.blogspot.de/2015/06/any-replacement-for-altera-epcq-devices.html  N25Q256A13ESF40G (EPCQ256 replacement) works fine for me with Arria V (ASx1 for me, but ASx4 probably works too). Or S25FL164K0XMFI00 (EPCS64 replacement) with older FPGA. I just disabled EPCX ID check and everything works.  But for gen 10 FPGAs, I don't know much yet about EPCQ-L. In the past with SOIC packages it was easy to unsolder and try parts, but now with this FBGA24 package, it will be harder... As EPCQ-L models cost ~40€ to 170€, I guess alternatives already exists !  ps: official spansion/cypress confirmation in this doc "Connecting Cypress SPI Flash to Configure Altera FPGAs" http://www.cypress.com/file/195256/download
